I think everyone that asks "what cam should I run" should watch this video first. Even if you don't know the flow of your stock heads, someone has flowed them and can provide some numbers. If you have aftermarket heads, they have already been flowed or if you have yours ported, Then you should have them flowed so you know. I didn't have mine flowed when they were done and I sure wish I knew. :BangHead::BangHead:
