444xs for 4.0 bore will get you approx. 9.0 c/r with 317 heads
444x05for 4.05 bore

so the K444X3 -11cc. because a 3.70 is a 4.030 bore with a 3.622 stroke. would i need to run a 6.098 or a 6.125 rod because the iron block deck height is .010 shorter than the ls1 block? by using the shorter rod would it lower the cr enough to get to 9.0 form the 9.2?
