Not sure. Thought they used the head off a 240 I6 to boost compression. Then you will probably need high test fuel to prevent knock, but should boost power. The 240 and 300 were build from same block design and so should be relatively compatable.

You could also have you head shaved or milled down a little to boost compression. I would check to see what ratio you are actually at right now and not go beyond 9-1 or 9.5-1 so it can still run on low test gas. If you go past 10-1 your looking at buying premium all the time. A machine shop would be able to advise you on how much you can take off.
