Heads, Intake & Carb upgrade...

Hey Kevin. I agree with about 90% of AJ’s post. The combo is all wrong and heading down a dim path.
Your head bolts, rockers are reusable. The pushrods maybe. A lot depends on if the deck was killed and how much and how much more lift the new cam has. I don’t subscribe to dumping the thumper though IMO there is a better cam out there.

If your pistons are far down in the hole, the compression ratio is going to hurt a lot. Can you measure this depth?
I don’t know about AJ’s 11-1 ratio. I don’t have the calculator out and I’m lacking information on the exact timing events of the cam.

As far as the carb goes, ether will do fine. I like the AVS over the DP in this particular case.
