What to do with my 360 magnum??

If you drill the heads it won't make it where you can't go back. They will work with both style intakes.

I was wondering about that. I may use your jig as a model, I kind of want to try it just because. Knowing that, I think I will put the magnum together mostly stock and just see how well it runs, and focus on my stroker. The magnum will then get swapped to my Dart Sport, but with efi, etc. I love it when my piles of parts start making sense!

UOP, to be honest, your combo sounds like it would be really fun and dependable!
