What bore diameter are you putting into the head gasket?
Have you looked up them piston to see how many cc dome/dish(above/below deck cc they have????
Glad you asked, I called federal mogul today and they told me that I could easily/safely remove 100.000 from the top of the piston if I chose, he also told me 7.6 for valve relief CC ( if I remember correctly, I left the exact info at the shop )

Bore diam I dont know yet cause I guess I have to decide on a head gasket first. I need to go thru this thread, look at my options as far as head gasket goes and then figure out what the bore diam is for that gasket.

Im assuming I need to figure out how much exactly the machine shop has to remove from the decks, then do my setup and decide how far down in the hole or above the deck Id like to be and with the chosen head gasket where I can get the compression.

I talked again with the machine shop today and the guy cutting the pistons, what came out of that was too get all the machine work done to the block first then Ill take everything back and set my pistons back up to re-measure how high they are out of the hole after they have cut and squared the deck.

Bring the pistons back to Matt and let him cut them down and then return them to the machine shop for balancing.

I didnt get the friends and family discount on the cutting of the pistons and so its not gonna be 50 for all 8 but 80. He said he does it quite often for guys that have mismatched engine components, his name is Matt Mercer, he is a fairly famous local sprint car builder/driver ect.

He also says he does it quite often for the diesel truck guys, something about there being a limited choice of head gaskets.

Pictured below is is milling machine and the fairly simple device to hold the piston
