60' help

Most of their big cams are +4, so they recommend 104 on a cam cut on a 108.

Putting it in even further ahead than that sometimes help low end if valve to piston clearance is good.

Be carefull jetting down in front, up in rear. You get the jet spread out of whack and it will create other issues. Any speckling on the porcelain?
