The Brodix RR have 119 cc chambers. With your pistons that will give you around 9.01 compression. That's a little on the low side for aluminum heads. Comp recommends 11-700-8,XR274R in a solid roller. Rpm range is 2200-6200. Also needs 2500 stall converter. The other cam 11-771-8,XR280R recommends 2800 stall, 10.1 or more compression, and 3.73 to 3.90 rear gears. KB 207 would have given you 10.2 compression. I like Brodix heads too.

Brodix also has the racerites in a 115 cc so that might help a bit.
