With 2 valve reliefs. First photo is the 2 barrel pistons. They could be flat tops as well if they have been replaced. The second photo is the high compression ones for the 4 barrel engine.
Nice, thanks for the pictures. I had a guy tell me the only way to know is pull the heads. By the power that this car has I'm pretty certain it's the commando motor. All I have to do is pull a plug!
I've had this car for 6 years and it's a blast to drive. I get asked quite often is it a hemi!
