Specs on L98 iron heads
Does anyone have the specs on stock L98 350 iron heads? I'd like to know the intake and exhaust port sizes, the combustion chamber size, and typical flow rates if possible.
Thanks!
Thanks!

Don't know the port sizes but the combustion chamber size is 64cc. Flow rates are as follows:
Intake:
@.400" - 178cfm
@.500" - 190cfm
Exhaust:
@.400" - 114cfm
@.500" - 115cfm
Hope that helps a bit.
