I need some advice here on what to do with my head!....Do i mill it, or buy after market, I dont want a girdle kit, I ride at 4000ft. and have 115lbs even, I want 145lbs to go along with my stage-2 kit!! Also does anyone know how much to cut for these results??

Thanks, Daniel.

Dan, i called Riva today but they were closed.I will call at lunch tomarrow and do some digging for you. Woody

I would recommend to buy aftermarket interchangable domes to experiment with compression also allows to travel with the ski or sell to someone who would be closer to sea level with out the worry about blowing up the compression and requiring high octane fuel.

Do the dome thing. Milling does not seem to produce and exact PSI. ADA makes a sweet head. They will alos cut custom domes if required.
