Thanks for the info guys. Quick question though pertaining to replacing 0331 head. im in the process of changing my head for a New "not remaned " J&C head and was wondering if i should also replace the pushrods and rockers while im there or will the old ones suffice. Old ones are still good not bent but id hate to fix something that is not broke.

the one that everyone seems to get is the dynomax "super turbo" it has a perforated s-pipe through the muffler. you check the dynomax website and you can see their options, i'm sure you already know that running 2.5" vs. stock 2.25" on any additions (thunderbolt cat converter or muffler/etc) will help flow a bit
