BBC Big M heads on 598?
I'm putting back together my 598 and have someone who wants to trade me a set of dart big m heads for my bb2x's both sets are not ported, and the cam I'm using is 799 lift and 288 duration on a 110 c/l running alky inj. and shifting a 4 spd at 7500 crossing the stripe at 7775. I want to know if its worth trading heads or not. will the big m's make more hp?
