thanks for the lack of help

Sorry about that. I needed some time. I did not have an answer right away to help you.

I talked to a friend of mine late last night who has tuned the Stage 2 Patriot head on a PI motor both with stock cams and VT stage 1 cams with upgraded exhaust, plenum, tune and TB. He didn't recall the exact numbers but he said the gains were about 18 hp with stock cams and 23 rwhp with stage 1 cams. It also depends on the overall condition of the motor -- compression etc. He said to take full advantage of any ported head, you have to change the spring strength and run higher lift cams to get the full benefit.

Use the search function, you'll be amazed at the results

Yeah i was saying the Patriots were not the best but better then stock. The tricks are the best
My point was just that getting the Patriots was better then nothing even if not the best.
and OP the search has just about everything you would want to know.
