Good luck with it. PRC makes a good head, are you getting a smaller combustion chamber to bump the CR or are you staying with 70CC?

I have my doubts you'll hit 500+ with that cam, especially if you arent upping the CR.

I have the same heads but went with 65cc chambers to bring my CR up to 9.9something. I also went with the hollow intake valves. You will have your dyno results before me. I probably won't get mine until May. They certainly are beautiful in person.

it really depends on your longterm goals. If you plan to stay NA and have access to higher octane fuel id suggest calling TSP and giving them your cam size and they can help you with milling requirements (CC's)

did someone recommend this for your blower setup? seems like someone gave you a bad recommendation based on what little I know. you should have went with a 68-70 CC to keep CR around 8.5-9 and also a stronger valve is ideal . maybe someone can chime in with more knowledge than I. |
