Thanks for the help ultraflow. I just found out Canton has no web site yet. One thing I wanted to mention to you when you do your buildup, I have had very good success with gaskets from Cometic.
www.cometic.com They make a MLS (Multi Layer Steel) composite that works great on the R302. You have to call them and the set is made specifically for you. If your bore is lets say 4.040, the gasket is made to that specific size. It is a bit spendy but re-useable. They claims up 15 times for Dyno applications. I also know a lot of the Pro 5.0 guys are using them.
Thanks again and I will check out FPS.
