Okay, since we're betting, I'm betting that the main bearings, rod bearings, cam, and cam bearings are fine. Replace all of the lifters, ensure the push rods and rockers are correct for the heads and valve springs, properly adjust the rockers and observe valve train geometry while rotating the engine by hand two times, use a different intake gasket than current, and put the engine back together. Go about your business.

If the engine then fails due to one of the things I'm betting are good, you then do what you might do now anyway. You're playing the odds and I'd like to see you win.
