I like the Tomei procams I got from you. Smooth at the 1k idle and pull all the way up.

 

How does the GSC 272's compare to the HKS 272's?

 

As far as performance goes probably not much difference. My first set of cams were the GSC 272's. But I had them only long enough to do a visual inspection. They just didn't seem to be a well manufactured cam IMO. The lobes still had an excess amount of material that could have been cleaned off, also on couple of the lobes I noticed alittle to much metal removed... there were a few small groves notched in the side of the lobes. They probably would have been fine, but seeing all that changed my mind to the HKS 272's.
