Default Roller rockers??? are they worth it??

Been comptinplating getting 1.8 roller rockers. Is it worth it, really don't want to cam it just rolled over 100k. Just trying to squeeze a little bit more out of my TA. Just wondering if anyone has installed any, what brand they went with, and what kind of results. Any input will help thanks.

I think people say you can expect ~15hp out of the 1.8 rockers. Whether thats worth it for the cost of them is up to you. If you don't plan on doing a cam and you have exhausted every other bolt on ... I'd say go for it.
I wouldn't let the 100k scare you on the cam though ... ppl have put cams in their higher mileage LS1's with success. There are a wide variety of cams out there that would give you more power than just the rockers and w/o having to worry about breaking things.

waste of time and money. Even cammed cars stick with stock rockers such as myself.

Untill you start finding needle bearings in your oil when you change it. High lift cams stress the rockers and many are known to fall apart.

You have to get the right springs to go with them. For example, I'll be running 1.8s which will give me about .600 lift with my cam, so I'm using PP .650 double springs which will give me .050 of headroom.

there supposed to make the valve train run smoother and free it up some, and get like 15hp "maybe" out of them.

Check out the Comp Cams #1500 system.

Adjustable to boot!

I am very happy with the results.

Instructions are crappy though.
