I wouldn't even consider the cyl heads until I was sure the intake wasn't the problem. In your case the intake is the problem. That's a fact

Consider this... Lets say your new heads flow 280 (big number) but your stock intake will only let you have 230 cfm of that. Do you think that is the recipe to hp happiness?

Intake will be your problem, that is a fact



Oh so true. First column is the cylinder head flow, second column is the head flow with the 1969 stock intake and an 850 Mighty Demon carburetor, third column is with an Edelbrock RPM intake and the 850.
