Scott just so you know Randy...Misty creek boats is a good source of info.We give each other crap sometimes LOL but he does know his stuff and is a good guy to take advice from, What he is talking about cutting is the amount of header that is beyond the water cooling section of the chamber, just leave a little past the second ring in there, Do not cut it super close but do not leave it stock length either with a mod motor the pipe being right is important. You will get it dialed in and do not except slow speeds just because its a big boat anything less then 50 mph even as a new builder means something is still not correct.
