I have FP diesel gaskets part no 1811050 they are stamped with the international part number my old ones were the oem ones from 89 they make them thicker because of milling for the heads to achieve the clearances needed so valves don't kiss the Pistons cause there is only bout .030 between them
Yes it's going to be std bore piston. my new head gaskets are .075 crushed. My old ones were .063 Measured at the fire rings. my heads were milled .007 and the machine shop compensated for that. So piston protrusion should be around .016 plus gained a little from the head gasket thickness.
If my math is good it's a value of 1.2 CR drop per .010 so it should put me around 20-20.5-1 cause the block decking is gonna eat up .010. I live in CA so it's not as much of an issue as it is with guys east and north doesn't drop below 30 here.
Ok guys here it goes finally able to post what I am doing as I have all the pieces in place for what I am building.

I bought a 7.3idi core engine from a guy near me earlier this week for 200.00 and was talking with him and he told me he had some extra parts laying around, so I said sure ill take them off your hands for you so he gave me another ZF5 syncros are bad in it and he went on to say he had another...
Ok so I got to the bottom of what caused the fialures. The ford OEM head bolts have 1.500 in of threads to grab the block with. The arp studs have 1.250 in worth of threads. the block holes are 2.500 deep with a 1.000 countersink and 1.500 in threads. With the lack of that .250 thread grab and...
I bought one thats off of a 1995 H1 Hummer its a idi Diesel fuel pump that produces 40 GPH and 7 psi with 9 max. Gotta watch the psi cause it will advance your IP if your not careful it cost me around 60.00 and change.
I used a 1/2-13 bottom tap the ARP tech said it was needed to clean the threads. one hole compleatly stripped out. five more of them partially let loose but then torqued down. I checked my brand new torque wrench against another one and it was good. some of the holes had alot of rust in them...
the instructions said thread them in finger tight so I did. And sorry if I wasent clear enough it was the block threads that failed not the stud threads.
I spent the better part of the other day installing my ARP head studs, cleaning out the holes and using a bottom tap to get them as perfect as I could. Soooooo as I was installing my nicely bulit heads that I got back from the shop yesterday with new pre cups and comp 910-16 springs and my...
