That is one sweet looking ride Steve
Roland does nice work. I hope you enjoy this forum better, lot's more action and very helpful people here.
There are some guy's who have some awesome exhuast to improve your motor. They also have a jackshaft set-up that I believe is almost ready for production. You can port your intake and exhuast and I think I read somewhere Norman has a post on how to port your head. There is the boost bottle set-up, some say it work's, some say it don't, I guess the only way to know 4 sure is to try it yourself.
