CNC Smolik Head

Excellent quality but wouldn't seal using only the rubber o-ring.

Smolik-CDH 110 / 58mm Bolt Spacing Aluminum Head

The aluminum head fits perfectly, and seals great using the o-ring head gasket. The head could be a little bit wider so it covers the cylinder cooling fins. Also could be longer on the front and rear for better cooling. The machining of the aluminum head is clean with tall angled cooling fins.

It's a must have thanks again
