J heads and roller cam

[BHA43]

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?

I would try calling Erson directly. See if they can get you specifics.

I will say this. Ported J heads that flow 260 cfm, with the right solid roller and compression. Can be good for 450-500 horse. Depending on your setup. So be prepared for that.

Of course I can't tell you what lobe separation you have but the grind is with their lobes R298/.422 & R306/.422. 298/306 advertised, with a .013 lash ramp (tight lash cam) 264/272 @ .050, .633"/.633" w/1.5 rockers, LSA unknown but probably 110.
