And Joe, I fully intend to measure twice and cut once...so to speak once I have all the things back in my hands from B & A.

Let me know when you get your rotating assembly installed. I will show you how or can measure your pistons and see how far out of the hole they are for you. I got lucky and on my 6.0, since the pistons were .013 out of the hole using a stock head gasket (cheap) put my quench perfect

Shoot for .040" of quench.

And don't listen to that guy about crap gas. 87 octane has more energy in it, giving it less resistance to detonation. if 87 will work fine in your engine, then there is no need to run 93.

There is a good article on tech about quench in the advance engineering section.

What Keith is stating is absolutely 110% correct. Keith, nice article on quench area. That one will be bookmarked and passed on when trying to explain this to others. Pat, after your deck surfaces are trued up, and your rotating assembled mocked up, you're probably going to find a stock gasket is close to, if not exactly what you need to obtain around or spot on to .040 quench. Most ding-dongs will tell you throw a .045 or .040 cometic on and be done with it. You could be cruisin' for a financial bruisin' if you did that without measuring. What would happen if your rods stretched slightly or your pistons swelled enough to smack the bottom of your heads? Disaster that's what! Get as close to .040 quench as you can and call it.
