J heads and roller cam

I picked up a set of ported J 2.02 heads set up to run with a roller cam, also got the Erson cam that was used with them part # E420999. No lifters or push rods. I plan on using them on a stock stroke 30 over 360 with KB 107 pistons that I have. Grind says 298/422 and 306/422. I can't find anything on the web on this cam. Even on the Erson site! I emailed them for info a week ago and haven't heard anything back. Any one here had any experience with anything similar?
