70 MACH I

Dan,
I'm retaining stock studs and using new Ford nuts (morlock Style), the gasket is a Percy guaranteed leakproof carbon/steel laminate, I'll let you know. I've used Earls laminated aluminums on a 80's 5.0 I had with long tuibes, (these gaskets are actually better than the Earls). I think I'll be OK, shorties are alot easier to hold in place, than long tubes. There is a hell of alot less vibrational stress on a shortie than a long tube. Mechanical leverage and all that.
