340 with edelbrock heads overheating

ok, thanks everyone for your responses.
The weird thing is not every cylinder has the issue where the valve hit the piston. Some are the exhaust valve some are the intake. Some pistons have a lighter impression than others.

Wouldn't if the cam was installed wrong this would happen to all the pistons, exhaust and intake valves?

Maybe the push robs were to long, or i got over zealous at adjusting them?

i see the edelbrock head gasket is thicker than the one i used. That could explain it too.
