SM Head Modifications on a budget

I certainly appreciate all the willing participants and mentors. I feel like I have gained some understanding of the whole process through this exercise. I hope to spend a little time the next few days cleaning up some loose ends and trying a couple more things. I don’t expect much until addressing the SSR, but I’ve got to try. I also owe it to Yellow Duster to try a couple of exhaust tests. Thanks again guys.

Thank you
