Roller rockers? I have 0 mods.
I plan on either building or buying a CAI soon.
Which rockers would you buy?
I want to make sure I never have to open the valve covers again after installing too.
I will eventually buy headers but from what I understand, you lose back pressure and the cars seem sluggish unless you have a cam or rockers.
07 GXP. 37,000 miles.
Thanks,
Tim

Take a look at dp 08 gxp's for sale thread he has some used crane gold 1.8rr with ls6 spring guide plates and I think push rods for $475. Its used but sill in good shape. $475 is a steal and they are good rockers.

I went with SLP 1.85 rockers and oil restriced pushrods since I didn't change the springs. Works very well and I got the rockers for $200.00 off of a member on this board. Something I could not pass up since the price was quite right.

1. If you are replacing rockers, make sure you replace the springs and rockers. If you are getting new springs, DO NOT get single springs. They are almost all made by comp cams and they break a lot.
2. The yella terra rockers are great but they are expensive and not made anymore. I would probally go with a 1.85 rocker as you will gain a little more then the 1.8.
3. As far as the headers go, its the second biggest mod we have. The first is getting a new intake manifold. Replacing the headers will give you very big gains, and the loss in back pressure is not a bad thing. It could be a on a turboed car but on a na its not.

also I have never had a problem with my comp. springs and they have been on there for a good while now. To be honest this is the first I've heard of it, but I also haven't been doing research either.
Finally, I agree with the headers statement and it wakes up even more when you swap the intake manifold. But remember you absolutely need a tune after a header install, there is no way around that. Also in case your wondered, you could never run the thorleys on a turbo set up anyway because of fitment issues.

Granted I'm not getting the full potential from my mods right now, but it's not a must.

harlend sharp are good too. and as far as the comp springs go, my shop has a big industrial trash can filled with broken ones.....they were really popular a long time ago cause they were cheap, but they are crap. The dual springs hold up a lot better.

Is it really necessary to change out the springs when doing the rockers and what about the pushrods? Thanks
Are these the rockers for any LS1 engine or what specific engine?
