Yes that kit would work together. We have in fact just done that kit, customer had heads ported else where , and they suggested that cam. Customer was not making the power he wanted , bike ran hot , started extremely hard( think broken ring gears and starter clutches). We swapped out his ported heads for a set of R&R cast heads, and installed a 1.800 t/b with a 51 mm unit over the bored version he had. Bike ran very well started easy, ran cooler and power wise I wil post the final dyno sheet soon. It will show a before and after for results.

It sure will work! Just be sure that you are using some of the heads that is not too large onthe valve sizes (Reggie and the boys have a half dozen or so "stages" of head work.) The 6HG Wood cam is a favorite for us here and will get you great low end TQ and will still be pulling with those heads in the upper ranges, too. Use a set of roller rockers and be sure to set up the valve train geometry spot on to keep the noise down. Just get your compression up around the 10 mark (or a bit better) and you are good to go.

I agree the cast head would be a great match with compression of 10.2 would get the job done very nicely. The valve size is the cast head is only a 1.940 intake and a 1.626 exhaust. With the extreme velocity & cfm of that head you will have issues at all with making power at any rpm range.

GRock, give me your ideas on valve sizing for that cam and the R&R cnc heads. Also does somebody have an address for R&R's website??

Rock was more talking of the stages of the ported heads, the cast are pretty standard with the valve sizes I listed above. You can get other sizes but what I listed is the most common used and will work with the cam and compression ratio. The cast head is a Stage V. We have pictures on the head on our site, and the address for the R&R site is www.rrcycles.biz

these are the best heads ive ever had. reggie sr/jr have been building motors for me for over 20 yrs and i couldnt say enough good things about them. they arent cheap tho, hp never is.

actually i had a force on there and it was starving for air. although it looks small the neck and elbow are considerably larger than the force/se/or whimmer set-ups. on the dyno it was the best producer for this engine. its a speeds performance high velocity air cleaner with a K&N filter. http://www.speedsperformanceplus.com/high-velocity-air-cleaner.html

i really havent tried anyother air cleaners. i had considered trying a horsepower inc at one time but was stuck on this look. later when i feel like another dyno run i may give a new one a try in the name of more HP/TQ.
