By looking at the pictures It’s still not clear what the differences are.
Maybe I’m missing something. Do the markings on the head determine
if the head are for dome pistons? I was told once that we’re the spark
plugs sit the round indention have two different sizes. The larger round
Indention is for dorm pistons.i don’t know if that’s a fact but that’s what
I was told. You should be able to just turn them upside down and see a difference but I don’t know what the difference are.
