If your interested in building power above 3600rpm BB. Open chamber way to go. Dont ask me how I know. Proper cam unless compression is unworthy closed is economical.

I've gone from closed to open chamber heads three times.. She's no race car, just want a 9.5/1 street car, I can enjoy and sell it....
