I'm working on port matching my RPM intake to my 670 heads with port opened to RAIV specs. Needless to say, the gasket alignment on the RPM is not correct, and I need to "build up" very small areas on one side of each runner divider, and grind the other side. Jim Hand refers to this process in his book, and recommends a "good fuel resistant epoxy". What should I use? I bought some JB weld, but am nervous to use it. Anyone done this without TIG welding it? I don't really weld, nor do I have access to a TIG. I really don't have the $ to pay to get it done. Any ideas/suggestions would be appreciated! Thanks!
