Use their inquiry form (e-mail) and supply as much info as you can. They do not offer stock grinds for 348-409 applications. They will provide info on your cam if at all possible. Erson has changed hands several times but has found a good home with PBM. They will help if possible.

I contacted them years ago before PBM and they didn't have much info on the old cams. I ran a 990=B for years. It was 622 lift and around 277@.050. Centerline was 113. I'd bet the BH is similar. The 990-B was a stone until about 3500. That's when you had to pay attention. Mine ran best when advanced big time . I put it in @ 103.5

That cam card is from a 990BH.
I got a 990bB from Tom Jacobson through Phil Reed years ago ago and it was a great cam.
My specs were 622 lift/277@.)050 and 113 lobe seperation.
I put it in @110 and gave me whiplash.
@3900* it would 60 ft1.46.
Best pass was 11.30/120
I'm gonna put it in a stroker next.
I also have a 990BH but it does have differant specs.

After Sig passed away, his son John took over the business. John's passion was VW's. I talked with John several times about making me some 990Bs to sell. Never could come up with the masters.
Later I heard he moved to Australia.

My, Bad. The 990 is fine. Ran it in my car for a long time. The 990BH has a bad lobe. If someone has the master, or can digitze it, they could make a new one
