I forget why but something to do with pushords and valve tip wear.

So far great results using the harland sharps though.

My understanding was that Trick Flow Heads, combined with OEM rockers could cause premature cupping of the ends of the valve stems. Additionally, my reading indicates that this has occurred on less than a handful of Trick Flow Heads installations. That is, I believe there are Trick Flow Heads installations out there being used with OEM rockers. If I am under a misconception, please let me know. In any event, I do not know that the valve stem wear is an issue with all Trick Flow Heads (i.e., 215cc, 225cc, etc). However, in an effort to mitigate such issues as those described above, I am going to compliment my Trick Flow 225 Heads with a set of Harland Sharp roller rockers.

Was that the final solution, no stock rockers? How much power do the H.S. for example cost? I've seen testing where it's huge up top in the rev range.
