Thinking about getting 1.6rr's. My car is all bolt on so far. Any advice in choice of roller rockers with 3/8 studs. Anything else I should replace or do? Do I need stronger valve springs and new push rods? Any help would be awesome. Thanks!

I like the Comp products, you'll get different inputs as to brand. Better valve springs are a definite and stronger pushrods are recommended as well. Depending which rocker arms you go with, you may have to notch the valve covers as well.

My advice would be go with 7/16 rockers (Comp Pro Magnum). Also get a set of chrome moly pushrods (Trickflow), guideplates (Trickflow), and a good set of springs. These upgrades will be a good base for future mods (heads/cam).

Awesome, thanks for the info, what kind of springs should I go with, maybe lt4 springs? Not looking for anything fancy, just something to support the 1.6rr's till future cam, heads, etc..

LT4s would be all you need for rockers only and they are cheap.

stealing the thread for a sec... will 1.7 rr fit under stock valve covers? and will the lt4 springs work with them also?

LSWHO

No.
I woudn't try it.

when doing springs can you just do springs only? no shims, retainers, etc

just got done putting mine on, crane gold 1.6 sa.,for center bolt valve covers.Had to change retainers and locks too,on engine and it sucked but it's done

HottestZ28

do you just buy a LT4 valve spring kit?

I was wondering about how to go about ordering lt4 springs and such as well. I know shbox has the part numbers on his website, but how many of each part will I need?

The bold part #'s I absolutely need, and the others are optional.

12495494 - lt4 valve spring set (set of 16)
12495492 - lt4 valve spring retainers (set of 16)
12495503 - lt4 valve locks (set of 32)

10212809 - Shims... Do I need these and how many? (part # for 1 shim)
2x 10212810 - valve seals, intake (set of 4)
2x 12564852 - valve seals, exhaust (set of 5)

I put isky springs rated for .560 lift but I was told you could put 1.6rr on stock springs not sure someone else chime in here, I am still on stock cam.I guess I won't have to worry about valve float.

What is better? Self aligning or none self aligning rockers? What do the non s.a. rockers require?- Extra work, parts, etc.?

NSA rockers are the best route,all you need extra is hardened pushrods,isky adjustable plates.While doing this you should upgrade to 7/16 studs...its almost like free hp compared to the 3/8 studs..

The SA rockers are the best bet if you just plan on doing the rockers as a standalone mod with no intent of upgrading to a bigger cam down the road.
