"I don't see how raising the compresssion ratio is going to make it a high RPM engine, diesel's have 18-22:1 C/R's and only run 1800-3250rpm."
You've got 2 completely differently operating engines, there. A Deisel doesn't run on the same principles as a gas engine. The high compression is necessary to raise the combustion chamber temp to allow the feul oil to fire and burn, as there is no spark in a Deisel. In a gas engine, generally speaking, a high compression allows for higher octane feul, and they generally are high RPM high horesepower performance engines. Raising the compression isn't going to fix the problem, and most likely will cause more problems than it will cure. Namely, if you have the heads millet, the intake and maybe even the block might have to milled as well just to make things bolt back up. Plus you have to consider the pistons, milling the heads could cause issues with the valves hitting the piston. I would suggest trying to find out why it won't run n 87, might be as simple as a timing issue.
