Cam/head design logic.

Kenny, what would you expect the RJ cam to do in one of Bos updated head ports vs a X-2?

The RJ should see similar top-end with real good gains down low and in the middle. Bo's head is working well.

how would a X-4 work with one of these heads?

This head should run with all the top dogs with the current crop of off the shelf cams, but it is designed to put some real daylight between us and them on the more aggressive cams. For the guys that are gonna stick strictly with the current cams, I will be selling them the good ol" Racers edge AZ head.

Kenny I have a mild port head on my 843 running the X2 cam, I find it very smooth. I just had the dyno done and it made 78HP but a wopping 68 tork.  How would your head do on this motor. (108 cyl with +8 strok) Stock intack and supper larg filter with your +2TB.  you can PM me a price as well.

Thank You

PS are you going to have or be at the Oregon raptor rally May 7-10th?

That depends on how good your current head is. I am used to seeing 6-8 hp at peak with that cam and +2 valves, but you will see very large gains in the overrev. If you combine this head with the FCI intake, you will see as much as 12-15 hp up near 8,000 rpm(last time I saw 15 @ 8,200). I will upgrade the TB from a +2 to a +3 for free if you get this head. Of course moving to a 52 mm TB will WAY open things up on this size motor. I have a head here for already cut for another customer that I haven't heard from in a few weeks, so it could be yours......

The pricing is the same as previous heads;
$500 CNC port
$140 valves
$200 springs
$840 total assembled

I should also have the new cams in next week if you are interested. There will be no more rocker cutting with these cams. The newest cams for this design are a little more flexible than the old style cams. Lift can range anywhere from .535"-.720" depending on application. Valvetrain geometry has really been improved on this head.
