I'm not gonna recommend roller rockers for HP gains. Ever. There is a long
laundry list of mods that would precede this purchase if in the pursuit of
HP. They ARE cool, and will decrease the wear on the guides and valve tips
if they are designed properly. I just wish for people not to waste their
money on mods that won't deliver what they are really after.
Everyone is certainly entitled to spend their caish any way they want, but
I'm trying to be a voice of reason, not a party pooper.
That is all I'm gonna say about that.
Jim
