Rods for 1.310" compression height Wound up with some JE custom pistons (not ordered by me) and all I've got on the spec sheet is "compression height: 1.310." Going in a 6.0 iron which supposedly has a slightly shorter deck than the aluminum counterparts. I've looked around a little but haven't seen anything solid as far as rod length. Should I run a 6.125" rod or a 6.100"? Would like to know before I ordered to avoid a return. My first inclination was to run the longer rod but I'd hate to be out of the hole and I would hate to run the shorter rod, have deck left, and knock my CR a little more than I would like. Thoughts?

comp. height for 6.125 rod=1.305 (figured at 0 deck and 9.240 deck ht.)
comp. height for 6.100 rod= 1.330 (figured at 0 deck and 9.240 deck ht.)

Well Wiseco says iron block has a deck height of 9.23, aluminum 9.24. No other piston manufacturer seems to make a distinction. In its piston listings, it has 0 deck at 9.213 for iron block and 9.24 for aluminum. Why not 9.23 and 9.24 for 0 deck?
