How is that nonsense? Why not regrind the cam. It’s a lot cheaper than a new cam! The videos stated right up front that they were going to do a rebuild with replacement pistons. Lightening up parts, grinding away at the head, just removing metal is what they said, right up front.
Paying someone to port and rebuild the head is pricey enough to consider new aluminum heads. Then again, if one could do the work themselves…….. Birds to cheap cheap cheap.
A single pattern vs a dual pattern cam is dependent on how the head flows as to which one will make better power.
If that’s possible, I’d do that. Dan doesn’t know the carbs are identical except the jetting. The intakes are identical. Year, make & model dependent, the truck could be minus a EGR valve.
Always make a plan and check with the smart guys!
