Rocker Arms? since i ordered from SLP before they are now selling performance packages....Stage 1 2 and 3....stage one is FlowPac and Exhaust Loudmouth or PowerFlo......Stage 2 has Maf sensor 1.85 ratio rocker arms...and a handhelpd PCM Programmer......3 is headers and catted Y....but anyways...to the rocker arms...would they be good to use with the stock cam and stock springs?....do they give any actual noticealble power?....are they worth it or not unless you have a stronger Cam?...would they need tuning?...what power will they make...and will they change exhaust sound or the exhaust note?
Is this worth it and what changes should i expect...and if they are worht it what is needed for there use?

a little more lift and other things associated with that effect, but more stress on the valvetrain. To do that swap you woul have to get their package with springs $699 I believe.
IMO too expensive for the "small benefits"
Forget that crap, get a higher stall and reward yourself with the pleasure it brings.
TCI 3000 is $450+ trans cooler.

power mods are being taken care of as well....no internal work for some time...i will be getting a stroker in the future so im not going to touch any internals except mayb heads and valves (if theya re worth it thats why im here asking)

The same company that makes the stockers. SLP's are basically the same as stockers but in a higher ratio.

Twisting is also a bad side effect of the stockers on high revving LSx motors. Shaft mounted cure that.
The issues with most aftermarket rockers are fitment issues on various head castings (Beside YT's and the KR issues)
If the stockers (or should I say when) quit spilling their bearings, I would stay with them because they FIT. (No grinding,hitting, spacers etc...)

Verdad Gallardo I agree about the needle bearing part, but that is a rare occurance that the bearings explode at most. Allan at Futral always reccommends stock rockers and said he hasnt seen a problem with needle bearings in over 3 years.

tell that to the dozens and dozens..perhaps hundreds of people that have had stock rocker needle bearings in their oil pan. Some people like Jason are just lucky.
Im glad you've tested all aftermarket LS1 rockers and know they all flex...whew..i feel better now know that...
Yea, I guess Allan at Futral has NO idea what he's talking about. And i seriously doubt Jason would put something that he relies on as "Luck" into his motor that's putting down signifigantly more power than your 383. I'll simply put it this way. Those guys have seen quite a few LS1's, not to mention HUNDREDS of hours in front of a dyno, and I trust they know what works and what doesnt.

Allan and Jason have setups that work for them, and they suggest stock rocker arms for whatever reason, but if the stockers were so great, why do people still swap them out? I wonder. 
Spend more then two months on this board, and realize that not everyone just blindly accepts shop owners word as gospel. Allan definitely knows his ****, but that doesn't mean I'm going to run the stock rocker arms cuz he said to. He's not going to be replacing and paying for new parts if mine fail.
Quit talking out of your ***. Its embarresing to see people do that. TECH Fanatic

aftermarket rockers are fine for stock to moderatly higher rpm range. jason uses (if i am not mistaken) stock rockers because he revs so high. the added weight of the roller changes the ballance of the valvetrain or something like that. Ask him and get a better reason why he uses stock rockers. I know one thing, he does not care if he blows a motor due to a rocker it would just be an excuse to change the setup
