Must have raised the roof and blew out the pushrod pinches and installed tubes to get that csa?

The engine is definitely a proven combo with substantial power and remarkable durability. I'm curious to know the cranking pounds of compression. Boris, he stated 1/16 compression and 3/16" oil rings. SKeown

If you go with 2.5" high and stock width of 1.14 on the gasket the csa is 2.736 then subtract for 4 radius's and it is about .100 off that so not sure how you got that csa?

Has to be the port and intake runner average csa added together to get that number.

It took this much grinding to match to a 2.64 minimum x-section.
