Ordered my headers, now I need new rockers

[surfsup]

I ordered my headers from Mac today, thanks guys for the help> but I just realized I need new rockers, I don’t think I should use the stock rockers, is one brand better then another? Not sure if I should go with 1.6 or 1.7.. I know the 1.7 will change the lift which is ok, I’m installing a Ecam with the heads but I wonder if I should have went with the B cam instead, the heads are SVO GT 40 aluminum, the guy I bought these from said there pedestal mount, should I stay with pedestal or change to stud mount, ? I was also thinking about used rockers to save a few dollars, ( any thoughts on used) if i buy used, are all rocker compatible as long as there stud or pedestal? or must they be for the right application? ford is ford chevy is chevy.This car is a daily driver, so it has to be some what trouble free
