4th gen m6 final ratio is .57:1 im sure it would be fine with 411. stock m6 should have 342 rear gears. might consider 390 for a happy middlegound.

Excuse me for changing the subject on your reply, but, now I'm looking to find a good set of roller rockers,studs, push rods and guideplates(?) (Do I really need new guide plates?) I've heard that 1.6 roller rockers with 7/16 studs is the way to go?

i went with some from tpis https://www.tpis.com/parts/view/125 also got the rocker studs and pushrods from them. https://www.tpis.com/caryears/listParts/14 you might find them cheaper somewhere else.

yes unless you already have guide plates. stock lt1 does not have them, has self centering rockers.

What would be some good guide plates? Any sizing?
Also any push rods you might recommended for my future setup and sizing?

least costly,,, lol, there steel plates so yah least expensive. i think i used tpis plates too. they had a sale going on and good prices for good products. lol.

got this info from lloyd https://camaroforums.com/forum/93-02...-length-51829/

here is what i have, pretty sure the guide plates were comp cam
ARP 134-7103 7/16 rocker studs
Trick Flow TFS-21407100 Pushrods, 5/16 x 7.100
comp cam 1305 roller rockers 1.6 7/16 pro magnum
tpis performance roller lifters

What are the plans for the car? NSA rockers and bigger studs are nice if you wanna go all out but if it's something isn't going to see any track time or very little, you're better of with SA rockers, imo.

I went with SA rockers and haven't had any trouble yet. I will switch to NSA when I go to a solid roller cam.

Self aligning rockers or guide plates, you do NOT use both. And since the push rods can/will contact the slots of the guide plates, make sure you use good quality hardened push rods.
Edit for clarification: I'm referring to aftermarket performance guide plates, which have closer tolerances to the push rods, not some of the (sloppier fit) factory plates that were put there merely as an assist to engine assembly.
