more hp w/ roller rockers????

[hard-charger]

hello everyone!  i had a set of crane adj. roller rockers, and they had enough  not to say they havent been kinda good, but they are done.
my question is, how much power would i be giving up if i switch to adj. isky 1604. which are not rollers, but they look bulletproof. i have a compleate set, shaft and all.  was thinking of useing them instead of buying new rollers.  im almost done putting my moter back together with a new tunnel ram, and kv3/kv4, cam from engle.
this is for a 440 w/ eddy heads. so..ya, if anyone knows anything about them isky adj. rockers id like to know. they came w/ a set of ported 906's that i got. thanks all!!!!

The Isky's will be fine. You're not giving up any HP on a street/strip combo with that rocker arm swap, inmo.

I agree the difference will be negligable
you could look at the Comp Pro Magnum stainless rollers as an option
