Also when I say they’re a perfect comparison it’s because at a side profile you can see that where the slope starts and goes up looks like it should be gradual enough to clear the quench pad. I know they are different designs completely but the profile shape towards the center where the concern is is close between the two and helps me get a bit of a guess. I have my mind made up on the pistons; I already have multiple sets of heads and I wanted to know mainly so I could get started refinishing the heads but I’m just going to wait until I have the pistons then I can just check. I’ve used these with 340 J heads before and they are fine and I have like 4 sets of those so I’ll use em if I have to. Just trying to get 10.5 ish dynamic compression and these plus the 302’s would help me get almost exactly there with the right cam choice. Not deciding on cam until I’ve decided on almost everything else
