Default heads: alum or iron

since keepin the head sealed is one of our biggest problems at what point do you need the flow of the alum head vs the strength of the iron?


say hypothetically on a 4.5" stroked tall deck with a 4.350" bore. e85 and twin 70somethings.

can you force enough air through a 270cfm port to feed this size of an engine at say 65-7000 rpms?



this would go into a strip car that will be street driven.


isnt there a 65(?) gto on here with twins and iron heads? anyone have a name/link?

thanx
