Hi all.

I found out that there is 1/10" differences between high(774-9137A12) and low(774-9137A9) dome piston, but does anybody have the actual dome height of the two types?
My existing 3 ring piston has P/N 744-9188 which I cant find referenced anywhere, and even though I don't mind mixing two and three ring pistons, I really would not like to mix high and low dome.
