I was hoping I didn't have to run heat.........Seems like an extra headache. I figured Tom's Cast Iron headers would help with that as they would hold some heat in that area unlike bent tubing.
If I go with a new Cam I'll bit for new springs. Easier to replace them at the begining instead of acouple thousand down the road.
Love Old '67-'72 GM Pickups! Dare to be different.....Running GM Inliners, GMC's MONSTER V-6's, and real inline power, Cummins, in Central PA.
