This is good to know. And yes I was thinking it was just a terrible camshaft selection in the 350 but now it makes me wonder if I have to remove the heads also if replacing the cam.

Yes, I just checked tonight after getting it nice and hot. The psi #'s were pretty high after advancing the cam with the below:

Driver Side:
  • #1 : 207 psi
  • #3 : 230 psi
  • #5 : 207 psi
  • #7 : 212 psi

Passenger Side:
  • #2 : 220 psi
  • #4 : 220 psi
  • #6 : 222 psi
  • #8 : 204 psi

Is that looking ok?
