Jim, i use an old beam type torque wrench, which might explain the torque difference.
Got the heads together, I switched to intake springs from pac , 948 triples in at 2.060, 350 lbs seat pressure. Exhausts use Pac 1247 springs, in at 2.005, with 330 seat pressure. Matt at PAC said i am good to 8500, but i never want to twist it beyond 7600 rpm.
I ordered parts to go dual lines from pan to pump since i wanted to upgrade to a new hose, figured i might as well add the second line.
