Hey bro welcome to the site. If I was you I would send the cylinders and head out to one of the site sponsors and get your self a dune port, head rechambered and shaved, ditch the T-6s and get a set of T-5s, and pickup an adjustable timing plate and advance your timing 4 degrees, Billet waterpump impeller, then throw a set of 33 PWKs and you'll be kicking their ass. I had Jeff @ FAST do all my port work he's a first class guy who knows how to make em go fast.
