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!I recently ordered a set of these head gaskets from Amazon.
Composition Material Cylinder Head Gasket - Up to 4.125" Bore - P4120094
If you are wanting to maximize your compression, these are the way to go.

2 eyebrows and flat-tops I presume? Sounds like nice pistons.Brand new, I was told 10.5 to 1 Ross pistons, I didnt see anything stamped on the pistons, I looked at the bottom sides and they have C45 looks like on the bottom side, I will double check this today. Thanks
The factory engines came with a steel shim gasket. .022 compressed. I have ran the 284/484 cam many times and with pistons .045 out of the bore. With the steel shim gasket. Kim.

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....

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