I have a 396 that is bored 60 over with stock heads. I am thinking to change to aluminum heads. There is NOTHING radical about the engine. It is a 396!
The 60 over 396 is what I have and what’s in the truck. Mild Edlebrock RPM cam. Pretty much bone stock. Just looking to liven it up a bit.
Is it even worth changing the heads and how do I determine my pushrod length.
