They would bump compression but make more power with the better port flow. Its a good sized head more ideal for higher rpm but a 6.0 has more cubes than the ls1 this setup was on. Pulled to mid 6000's with the small cam and held well to 7000 rpm shifts

Flow on a local bench showed 272 at .585". 193 exhaust flow at .600. Seems lower than most benches, think stock 243's dont flow over 240-250 on this bench. They are an older patriot head, may not quite be 227cc but run hard on the ls1 it came off of
Bump!
Bump!
