I was talking with a friend the other day about his planned B20/B21 build and we got on the subject of camshafts. My 1st thoughts were Web & Crane and then I remembered an old school company; GUDE. I emailed them and the owner got back to me, they still make camshafts for B20/B21 and H23a1. I know there were a lot of Gude guys around back in the day, because nobody really had options for non-vtec guys.....
Just trying to help
