The head casting number for the driver side head is 4027593 which is period accurate. What I read said it is for non-air pump equipped models. What was the air pump for? The carb is a proformance 650 and the intake is an Edelbrock LD4B.
Also, I finally figured out that a "302" head refers to the the last 3 casting numbers and not the displacement of the engine it comes from. I found a source for rebuilt 302 heads, so I'm considering swapping the current heads for those now. If I do that does anyone know if the COMP 252/252 cam would work well? Vehicle is like 3,800lbs.
