i was lookin at these two cam specs from comp. the 268h npi cams vs the 262ah pi cams. this may be a dumb question because i'm running pi cams now but, whats the difference performance wise. i mean would it be better to run pi cams or the npi cams in my car. i'm assuming since the pi cams have .05 more lift that those would be the better choice to go with right?? i'm stickin with the npi heads so would the pi cams be the best choice or should i stick with the npi grinds? i'm kinda confused on this topic because if the pi aftermarket cams work in the npi heads why even make the npi stuff anymore???

If I remember right, it's been a few years since I messed with a set of npi heads, the valve guides were too tall to allow the cams to open the valve anymore, which was easily taken care of by a machine shop. I also believe they had a set of offest retainers that were supposed to help also. But I'm sure something has change in the 5 years since I touched an npi head.

but the pi cams lift to .5 and they fit fine. weird. can someone else shed some light on the subject?
