If your going to that amount of trouble just get a set of eddies and have Modern Cylinder gead CNC them. Those Brodix heads arent much if any better than well done Eddies. Or wait for the Trick flows.
Have a buddy with B1BA heads. His are ported, car is 200 pounds lighter than mine and is only tenth and a half quicker than me with mildly ported eddies. Both similar builds, both stock stroke Smallblocks. He actually has more compression
