A close-up of a Ross piston. The bottom looks like it just came from the shop. The black coloring on the skirt is Moly-Cote from Swain-Tech coatings. The gold-colored band just above the skirt is the Gold-Top coating, also from Swain-Tech. I need to see if you can get pistons recoated...if I can find out if the pistons will give me 11.0:1 CR as they are or if the were meant to be used with the DPR head. You'd think I already knew this, but no. I'm not that bright.

A close-up of a Ross piston. The bottom looks like it just came from the shop. The black coloring on the skirt is Moly-Cote from Swain-Tech coatings.

A combustion chamber from my DPR head. Notice how it was reshaped in more of a figure-eight (called a clover-leaf) pattern. This would have been great if they hadn't then screwed the whole head up. The valves are supposedly 1mm oversized: When I pull it apart I'll post them side-by-side for a comparison.
This assembly... the F, drivers suspension...is the bane of my existence. The driveshaft is so welded to the hub that I broke a big 2-jaw puller trying to get it off. The other end of the driveshaft is wedged in my tranny and refuses to budge, thats why the CV joint is destroyed:It gave out before the retaining ring on the shaft.
