Ok, I have another question. I did a build of a 78 400. The shop milled the heads and decked the block but he said it wasn't enough to matter.
The problem I am having is that it won't time. It back fires thru the carb. Nothing I do to change the timing helps.
I have desassembled it down to removing the cam and putting it back making sure everything is right. It still does it.
I used the stock push rods. How do I tell if I need special length rods? That may be what is holding the valve open and causing the backfire.
