.100 below the deck,,,that is not good.
There is no quench action going on there.

Are you sure it is .100 down & not .010 seems a bit excessive??

That would mean you would need to wake off .100 off the block to get zero deck.

I believe I have those pistons you have & milled them to be flat tops w/no valve relieves.

After the milling I did , now I would have to mill the block/deck down .103 to have a zero deck.

I can look @ the PN on my pistons to see if they are the same as yours,it's been a while since I looked @ mine.
