Unlucky Test 13: S/R Torquer cylinder heads (January 2003).By Test 12 we had really started to crank out some power, especially considering that DM still wore its stock iron heads and ran a mild camshaft. However, Test 13 really did prove to be an unlucky number, and we were taught a lesson in proper parts matching. The S/R Torquer cylinder heads (which we got from Bill Mitchell's Hardcore Racing Products for only $415 each) set us back a few ponies, probably the result of combustion chambers and valves that were too large compared to the stock heads.
