Re: Flow #s for Stock Heads? More like 2900 for MTI S2 heads. And yes it is worth it. Everything works as a system. When I tuned and put 100 wet shot on I got 135rwhp with it! Better you breath, the faster you will run

Re: Flow #s for Stock Heads? The LS6 heads will not show much gain with your stock LS1 cam. Now its a different story if you decide to drop a nice cam in it, then the stock LS6 heads will show their stuff. Now you are ready to get them ported later for even more hp.
