Torque monster
By: Air2air
Tony and Jamal at MM put this big-valve unit while rebuilding my short block after I detonated and melted a rare ported 12G938 head. Night and day difference, especially in torque and temp control. It runs 20 deg. cooler. They added the MM103 cam. It does use the larger RA8HC spark plugs and I've noticed much more even coloring between the 4 plugs than on the old head. The head also looks better than anything else you can put in there, I think.
