OST Cylinder Head Porting Services

[oldeskewltoy]

A quality port job can add power,and ECONOMY, even while retaining stock parts! Because casting imperfections are removed, not only are power gains likely, but more even airflow promotes even combustion, which promotes cleaner emissions. More airflow, more power... less throttle angle required to hold a speed... likelihood of better mileage (if you can resist the urge )

BIG EDIT - Since I ALWAYS recommend a minimum level of work, I decided that pricing should reflect that minimum amount of service. I've condensed the bowls, and seats, tapering the guides, deshrouding and balancing the chambers, and the exhaust port re-taper into the minimum service I'll offer.

$600 (minimum service) to do the 16 bowls/seats, taper the valve guides, deshroud and balancing chamber volume, exhaust port re-taper, and polishing.
$150 to blend the intake guide bosses and to re-taper port roof - largeport
$175 to blend intake guide bosses, blend port walls, and re-taper port roof - smallport
$125 adding intake side oil drain
$100 for machining of the heads surface
$80 for cam journal deburring and polishing, and overall deburring
$80 for hand lapped valves
$60 for re-assembly
$60 to set valve clearances - your supplied camshaft

Loynings valve jobs - a few hundred to a few thousand

When ever you are ready Ronny...

I'll be happy to massage a cylinder head for you.....


Here are a few of my previous builds - https://www.google.com/search?q=oldeske ... 96&bih=604

do you know what the average cost is to ship a head? im a bit interested in your service. thanks let me know

[oldeskewltoy]

do you know what the average cost is to ship a head? im a bit interested in your service. thanks let me know

from most areas in the USA... somewhere between $30 and $40. there is some cash to be saved by shipping USPS. Return freight is usually a bit more($10+) because I typically insure it for $800-$1000.

[oldeskewltoy]

Short radius shaping....

Above is Port #4... here are the other 3 ports.......


Port 3



Port 2



Port 1




Hmmm, I think I heard you..., "What does an unported short radius look like??" Well I don't have a photo of those (ports above) prior to work, but here is another head showing the short radius before...



and after.......


Interested??? Send me an email - oldeskewltoy@yahoo.com

cool thanks for that info your work is VERY top notch

[oldeskewltoy]

Bump...

checking/verifying chamber volume.....



A bit of custom work to provide adequate clearance for those BIG cams....


As well as doing the detail work that others don't......

Before (all except bottom left)


After........



It just doesn't get any simpler - view the exhaust port on the left as it goes from beastly to beauty........

VERY shortly I'll be offering flowbench services. I have not as of yet figured out how much I'll be charging. I also will not be offering this until I feel I can guarantee my #s.

To do this I've recently acquired some new equipment....



and so I KNOW I'm accurate with setting valve lift...






I've also had quite a few people help "train" me on my own equipment

the math involved in the flowbench makes my brain hurt ... so I've had a few people help dumb the theories down for me to simple actions(keystrokes) to operate "the tool" = flowbench



One service I'm planning to add to a minimum service.... is to show on a flowbench spread sheet, the progress of one cylinder from dirty/cruddy/old, to cleaned up original casting, to fully ported and ready to deliver.

I also plan on doing full port matching. This will be based on an hourly rate I'll set in the future.

Now TRUE port matching has nothing to do with hogging out the hole to fit the gasket...

What TRUE port matching is.... has EVERYTHING to do with making sure EACH PORT flows the same @ each lift point so that each cylinder get an IDENTICAL fuel/air charge so ALL cylinders are making the same power.

[oldeskewltoy]

Sorry for the hijack, But is there a post somewhere with before&after flow numbers, or a percentage if you don't want give up the numbers? d:)b
I haven't taken look at much of your stuff, kinda gave up after too many polished ex port pics.

Why yes... I DO have PROOF of what I can do......




the little red arrows are pointing to 7.1mm lift, or cams from 1988+ 4AGE engines

the blue arrows are 7.5mm lift from the earlier pre 1988 4AGE engines

As the arrows show even with stock cams, my port work improves flow. Btw, those numbers were back in 2009, my exhaust port work has improved since then.

Not just 4AG..... currently working on a 7MG head... OST-022 - viewtopic.php?f=12&t=4927


Checking the flow on #5

[ssspacely]

what is your turn around time? I am interested in upgrading to mild cams as well. thanks.

typical turn around for my work is about 2 weeks, add in a Loyning 3 angle and add a week.

best to send me an email to oldeskewltoy@yahoo.com

[sekang0]

Might be a long shot but wanted to see if you have a spare smallport head you could sell to me? I'd also need it ported too so all those charges for services would be added on of course. Thanks!

don't have one on hand now... but I can get a hold of one in 3 to 4 days... send me an email to oldeskewltoy@yahoo.com





As to what I've been doing recently..... I'm porting a head from a Mazda(Ford) 2.2 liter turbo. A few pics for you from that job....

exhaust work...





Chamber deshrouding




Intake bowls...





short radius, and port roof...





Stay tuned.... rumors of a certain 6 have come to light

[oldeskewltoy]

Do to Uncle's Sam, and Kitzhaber requirement for taxes... beginning with OST-027 my prices will rise... (see first post)

I'm sorry... but I have kept things pretty steady for the past 4 years....


And now a distraction - Some recent work

[Reuterskiold]

Hi this is slightly unrelated but I figured since 4age head work is what you do, you might know these numbers off the top of your head



hello all, I'm in the middle of rebuilding a Small port, it's a mild build, balanced bottom end, .020 over, etc........ I am sooooo close to having it back in my hands but my machinist just needs a couple specs before I can get it. so i was wondering if anyone would know off hand some numbers...
WHAT IS THE OE HEAD GASKET THICKNESS COMPRESSED?
OE PISTON TO DECK CLEARANCE?
OE VALVE TO PISTON CLEARANCE?
thank you for your help

1.2mm is the OEM gasket compressed thickness.

OE Piston to deck is unreliable... I've measured USED engines I've ASSUMED are original @ .002" to .003"

The OE valve to piston is somewhere in excess of 7.5mm because the engine is none interference and so with stock cams(7.5mm lift), the pistons do not hit if you break a belt.

[oldeskewltoy]

Been way to long since an update.....

getting those cam caps deburred, and buffed




getting the intake bowls just right to optimize flow




and we can't forget the exhaust work....

[oldeskewltoy]

Some recent 20V work..........

exhaust side....



and a bit from the intake side... with a bit of negative effects to better highlight the work performed



Send me an email if you are interested in port work - oldeskewltoy@yahoo.com

[oldeskewltoy]

New service - adding an intake side oil drain - $125.00






Advantages: 1) minimizes some oil blowby (that happening on long left hand sweepers), 2) helps oil drainage from the head

[oldeskewltoy]

Not all my work is on 4AGE heads...

SR20VE





BP-VE (Miata VVT)

[oldeskewltoy]

does anyone know of any good cylinder head porting places in north qld, with flow bench and all the proper gear to do it?

I do ship heads world wide........ oldeskewltoy@yahoo.com

Whats the turn around for a stock blue top ported and polish and angle job?

Location is los angeles.

it depends.... right now, it would be about 8-10 weeks ( a few jobs lined up) When I'm slow, 4-6 weeks.
