When was the last time you personally dropped the pan and checked the main & rod clearances? If you haven't this would be the first thing to do. Are the journals standard size or under? If they are a lot under (0,040 or more) from a regrind your Babbitt will be thicker and less likely to take as much load. I've also seen some re-Babbitt jobs with way to thick shim packs that create overly thick Babbitt that will not take much load. Also pay attention to how much crank end play has developed.

If everything checks out OK after checking and adjusting the shims you should be good to go for any head that bolts on! The Snyder's 6.0:1 would be good if everything else is stock. You'll need to run a bit less spark advance.
