Troll, heads have smaller than stock ports but flow more than what actual reputable shops and all your prices are cheaper.

I know Tony aims for 1.45 port efficiency and gets that on the 220's on a 3.9" bore. Your numbers are 1.5 port efficiencies on a stock casting?

My old ported heads were reported by the speed shop to flow 285 at 600 lift, and the best I ever got off them was 370 horsepower.

So I just bought this MS4 cam with 7.4 PRs for my stock ls1 with 241 heads...well I just found a nice set of stock 243s and I was wondering will I be able to use them with the cam package or will i have to fly cut the pistons?....or should I just check ptv and then make that call?
