hello everyone,
I'm new to diesel performance and i have a 05 cummins and i was looking into some head work. whats the best thing to do ,head studs, o-ring, stainless steel valves with stiffer springs, port and polish???
Ive seen some people port and polish just the exhuast side, why not the intake side? is the gains not as good on the intake side compared to exhuast side?
