I spent a while looking, but never found anyone who had flowed a 5V head before... so I did.

That is pretty good, especially considering valve size.



As to bench racing numbers, that port should support up to about 340-360 n/a hp

centerlines are now known... and my guess was wrong........   I had thought they were 116+ do to the smooth idle, and the short powerband...  I was wrong!   The cam has a 110 degree centerline....  no need to screw with moving it!   So, the word is out to the cam grinder that we want to twist this baby to 6000, and to get as much lift as we can - do to base circle, valve lift will be about .450"

Woot.

I'd wondered how long you would be forced to chase the head gasket before I quietly chipped in the custom cut annealed copper idea. Local race shop was fond of it when they did oddball motors or o-ringed setups. I know they did more than a few sans rings, not sure if they were race team service interval type builds tho.

I know they sent more than a few out the door that way - but they also used to sell other customers "new" parts that came out of other vehicles in the shop and randomly bolt things back up without the right internals. :evil:

Happily they went under pretty much right when I heard this from some acquantainces that worked there.

Less happy is how they finished that process - depending on your outlook :lol:
