Thanks! I'll remember that next time, hard to find mail order for less than $80 a pair.

It's too bad that these Mopar ones aren't available in their original form, part # stayed the same but their now a 40-42 thou composition offering!

2 eyebrows and flat-tops I presume? Sounds like nice pistons.
If they are Ross PN 99625 then the deck was cut a lot more than .010" if these are really sticking out of the block by .025". Have you actually measured this .025" out of the block? This Ross PN starts out .036" shorter than the stock 340 pistons so would be about .018" below a stock uncut deck.
IDK if Ross coulda done custom compression height pistons here....

way above you said you have 10.5:1 pistons
just a advertising number
do the half inch down measurement and calculate with ccd head and gasket
only way to knoe
and you do need to know
blending valve cuts is a good idea before you measure

Nice finish on the deck. You may have gotten something pretty good.
