[QUOTE=GTX JOHN;695987]I did some checking and the 68 to early 70s pistons have
4 VALVE notches similar to 72/73 340 engines.

You need to use them rather than flat tops or you will have
nearly zero valve clearance with a stocker camshaft with
correct lift.

Sorry I did not know the early engines had a different piston.[/QU

ok, guess i will just have to go with the ross pistons. the class whides to not mention the valve reliefs
