Comp cams will tend to make you cry -- a lot. Their (and other brand) off-the-shelf aftermarket grinds tend to be stuck in the pas, and usually are just Chevrolet profiles (hooray, you give up the advantage of the slant-6's larger lifter diameter).

Get Doug Dutra's RV10RDP or RV15RDP grind. Where and how to do so is an open question since Erson changed hands. Read this thread (plus links) and then here.
