The high compression head could be the last finial stage increase. Only swapped on using the equipment that had already proved to gain the most power. What I worry about is the fact that it takes so long to just optimize one engine combination. It isn't just a matter of swapping on a new part. Changing one thing generally means changing the fuel mixture and timing as well. However it goes, it will be very enlightening and probably lay to rest a few myths that have evolved through the years. My hats off to you just for the effort. Checks in the mail.
