RIP

Less weight & move the engine back. If you've got a min. weight, add it back under the seats. // Also, was thinking a NO2 bottle, a small one under the dash or gutted heater/AC box, like the bottle for paint ball guns. Elec switch/valve & run thin nylon/teflon tubing inside the heater hose. ...

Assuming they're stiffer, higher durometer, I'd mount'm, engine/vise/frame and then twist/move/whatever the other end with an adjustable wrench or drift punch in a hole and just go by their feel.

Checkout YouTube for AC compressor shaft seal replacement/leak/fix.
Some are easy, some ain't, some special tools, some not.
Keep it CLEAN, no surface problems, scratches, nicks, whatever, on the 2 flat smooth surfaces that push against each other, and the shaft & housing.

What's the specific question?
oldeskewltoy has had A LOT of threads about heads & checking volume on this site, and at least 1 gotta be about that head and if he hasn't answered it, it's not a good question.

Thanks.
Beautiful.

... I have to try several times to crank it, at times it cranks but with a very low RPMs making a noise as if it getting limited fuel. Can it wind out 2nd & 3rd gear, 5-6K rpm without any problem, before the problem starts? If so, there is no fuel problem. There may be a not really a fuel probl...

Around here there isn't a specific number, just a sticker on the pumps "May contain up to 10% Ethanol'.
I think most all decay stuff has been BS, but it doesn't age very well at all & really turns really nasty.

No.
And I'll say that is not a guess, and I'll say that the amazing jondee86 & oldskewltoy would never guess that also.
Water corrosion, sure, but never seen one localized like that unless the engine was leaning over.

I wish I knew what that pic is.

New bolts won't be as smooth, thread & head, as old so you might actually be tightening it less then before.
Yes, thin gasket will retard the timing, head cut even more. How much? IDK.
Good luck.

IIRC, I could give the heater a quick feel while driving, but you're RHD. Just a one time confirm the heater's venting is open & what's blowing is what's happening in the core. The heater's outlet goes right to the thermostat and cools it down, slowing the flow. That's as much as I'm able to gue...

Maybe somewhere in the below...

All the above. Yours might only need some tuning. clean its terminals, clean ground if it's 1-wire, clean its relay terminals & contacts, adjust it. That adjustment screw on it, self tapping or threaded& locknut, will change it quite a bit until there's no sound at all at either end of its r...

OK.
I'd think that big aluminum ridge around the seat would do more then a bit, but I've got 0 flowbench experience and can only go by what looks aerodynamically pretty to my eye.
Thanks.

Water pump failure is extremely rare, I've never seen one but I've heard of Many water pumps being replaced for reasons only slightly related to it. Not that water pumps don't fail, they leak & their bearing goes bad, but failing to actually pump is almost unheard of, a few have broken impellers...

Thanks, looks nice & clean,
Looking at those 3 valves through the intake is always a neat thrill!
Were the other cyls clean & dry & smegma free?

Is there going to be any more finishing/grinding the comb chamber, all the area after the 45, on the 60 to 90 and the ridge around the seat?

...comes very close to the yoke during rotation.

Heatshield?
Contact after abuse counts, like a little kiss to the dirt & coating, or like it's been hammered on?
Rebuilds not inspected and/or disassembled are iffy, otherwise great & can last a long time.

Big chamfer, still need a ring compressor?
Thanks, beautiful work & pics.

Wow, that's a new one!
If the guide's top isn't normally submerged, extra seal or no seal shouldn't oil it up that much, besides it's only 1 exhaust & isn't going to affect the other or the chamber.
Burr on.

Any air leak enough for 7K oughta be loud enough to hear 10 feet away, with the hood closed.

My guess

Good luck.

Are you talking about shorter - length -, or a shorter shoulder, that un-threaded portion under the bolts head that is a close tolerance fit into the flywheel? Too long will bottom out & not clamp, its gotta be right! Automatic flex-plates must have a shorter bolt. A hacksaw should take care of ...

...what tools are required... Required? None, except a piece of tubing, mechanic's stethoscope or one of those tube type airline headphones and halfway decent hearing in one ear. Listening to the hiss at the same position on each one will easily get you within those marks on the Unisyn's scale. IDK...

Yes, if you consider all the charcoal canister & fuel vapor stuff as BS.
Gasoline used to take a long time to age, now with the alcohol(or maybe even without) it ages quicker, and venting to atmo might make it even quicker.

Thank You jondee86!! Aftermarket isn't smart enough to include a necessary feature, but they are smart enough to know you aren't going to return it. All it needs is a vent like the agcoauto pic jondee86 posted, it doesn't have to be too big, even 1/8in 4mm ID oughta be just about large enough. It do...

The tank's filler neck has a small tube inside it that goes down past the end mounting & turns up into all that space above the entry into the tank, it's a vent. The stock tank, not the poorly soldered aftermarket. When that tube gets fuel in it, like the airlock/p-trap on a kitchen sink,it stop...

Thanks Jondee.
Lube be good.

Bore distortion is very pronounced on some blocks, not so significant on others, Any cylinder boring is going to weaken it and higher head bolt torque will increase the effect. EVERY block deforms, its just a question of how much. Does your bore wear look different between the head bolts Vs adjacent...
