Currently using ProMagnum 1.6s non-sa but before this I ran ProForm 1.5 SA for a few years and like 45K miles with good results.
Tried a set set of CAT 1.65 SA which measured 1.6 and I was afraid to leave them in, some friends had MAJOR issues with them.
I wouldn't use proform rockers because they appear to be cheaply made and I've heard of people having problems with them.
No problems here, clear any valve cover Ive tried on, and my rockers are ALWAYS centered on the valve tip.
Unlike my buddy's AFR headed 355. He used ProMag 1.6 non SA with AFR supplied guide plates. None of his rockers are centered on the valve tip because of the guide plates. No matter how we adjust it.
