Quick question for you, since I know you run PRC's. What valve guide material do they use with their heads? Thanks.

Unreal is right . Port the stock heads . I currently have 3 sets of ls7 heads . 2 after market , 1 stock All ported . The stocks are just as strong with same runner and valve size . Don't race flow benches . Look at who is running fast , once again as unreal suggested, and then make your decision .
