Default Help me out on rocker choices?

Ok, i was going to get some new 1418 comp self alligning 1.6s for 145.00, but got to looking around & found some (slitely used) # 12370839 GM Aluminum 1.6s for 150.00, are these a good rocker for street use? I also found some new (SA) Full roller rockers for 169.00, now i don't know, the full roller look sweet, but i'm wondering if the adjuster on these (& the Aluminums) will fit under the stock VC.

yes an aluminum full rr will fit under a stock vc. i'm running the crane gold 1.6 under mine. i've also used the comp pro mags. love both.

The 12370839s look like a crane gold style, but not a full roller, the ones from KMJ are a stainless full roller, but they sure look sweet, so which ones should i get, hhmmmm.

Funds are tight, i'm sure the comp 1418s aren't chromoly neither, but i'm really leaning towards the stainless full rollers.

the stainless looks like a really strong rocker. I'd go with those.

I'll see if they have NSA, but i'm not looking to turn high RPMs, i'm getting chromoly pushrods, ARP 3/8 studs, i don't see why this wouldn't hold up.

I'm using the GMs, but not the 1.6 ratio. So far, I've got about 30,000 miles on them with no issues. And yes, they fit under the OE valve covers.

be careful of some of the cheaper aluminum hollow body rockers, I've seen enough break to be weary of them
