Super Charged Slant Six

FYI Bill, we stuck 1.81" int/1.55" exh valves in the heads. Had to unshroud the copper head gasket and cylinder walls for the intake valve.

see thats near what valves i was looking to run... maybe even a slightly smaller exhaust valve and bigger intake...

and for bill... thanks for giving me a reference as you shown above...

this helps alot in placing goals for what i can make happen...

my next question would be do you need a 2.02 intake valve to flow 300cfm??
