Re: Patriot stage II cnc heads, comp xer273 cam

Would those heads be good on the Lq4 in my pickup, or overkill?

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

Re: Patriot stage II cnc heads, comp xer273 cam

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!

I had a set of older (unmarked) Patriots on a 6.0L LQ4. Quick car and had plenty of breath to nearly 7K rpm with an MS3 cam. Had to fly cut the pistons for clearance.
