Re: Chevy 4.3 V/6 education needed
for heads i would stay with the stockers just the basics 3 angle,if you really want to get aggressive have them fitted with 2.02 but that all depends on what cam you run. The bottom ends being 2 bolt mains were a weak point on spinning it up or anything with boost. I have converted mine to 4 and keep boost at 22-25 with the stock cast cranks with no problems now.
