Domes are solid as said...I have a set in a 340 with domes cut off...you can barely see the spark plug indention...somewhere in my shed I have a set of those dome pistons that are .060 over....ran that engine for about 10 yrs with Av gas. back in the 80s....
70aar... how was this engine used? Strip? Street/strip? Nice that they have been used by someone here, but I think it would be more useful to the OP to know how they were used.
