Ripped the head off my magna today, a surprising feat considering my tools were about 3 spanners, screwdrivers and a hammer :P

Anyway, i want to rebuild it as a performance head for my siggy (already running a magna head) and im not sure what to do about rockers, i want to ditch the old magna hydr ones, but should i get roller rockers or sigma solid rockers?

What i can see against roller rockers is that a cam for them is about twice the price, but i do want a nice track motor, so whats best?

Btw, the plan for it is a RPW Stage 2 cam, mild port work, and a general recon
(for some reason i couldn't edit that post :S)

You will need the sigma arms and rails because the std hydrolic units dont have enough adjustment for the reground cam.

Other than that, go for it!
