Do I Have The Right Cam?

Hi Guy's

A few years back I put a roller cam in my engine and I was wondering what you guys think about what Comp Cams recommended. First off I wanted to say that the cam I purchased from them was a hydraulic roller cam, but when I tried to install the lifters into my engine the push rods were on an extreme angle and were rubbing on the opening where the push rod went through the head. It seems that the lifters were taller and that was what caused the problem (so much for direct fit huh?). Anyway I wound up using the solid lifters and they fit fine, but I'm not sure if that is a problem being as the cam was designed for hydraulic lifters. I have included a scan of my cam spec card. P.S My engine and drive train specs are listed below

Thanks For Your Opinion.
