That part number is returning any pistons on jegs or summit's websites.
Assuming the deck has not been cut (aka standard deck height of 9.025") and with standard compression height pistons (1.560") you have .025" deck clearance.
Then top that off with a .044" head gasket...
That gives you a .069" squish. That is too much IMHO. Shoot for .040-.045" squish.
Typical rebuilder pistons will have a compression height of 1.540", which in my example above would give you a squish of .089" which is way too much!
Now has the block been decked?
