1.85 roller rockers worth it??? I am getting another ls1 and want to mod it...but i don;t want to tear into the motor too much of this one....i was looking at the 1.85 roller rockers from slp and i was wondering if anyone has used them and if they are even worthh it??
thanks

It depends on what YOU think is "worth it" Full roller rockers can and will give you more horsepower due less drivetrain friction and ratio. If you are really wanting to get the most of your ls1 then sure go for it, but if you cannot justify spending X dollars and getting X horsepower, then no it is not worth it. I was going to put 1.8 rockers on my ls1, but instead I decided to go with a more aggressive cam and PTV issues came up.
I do have some for sale on ebay if you are interested in some really sweet rockers.

aight guys, i already got springs, pushrods. but i was reading in GMHTP about these roller rockers and the power increase. I'm also going FI with a STS turbo.
would buying the 1.8 or 1.85 roller rockers benefit me a good bit for the application i'm installing?
i heard of gaines of 17rwhp+; to me thats worth it
also, where can i get JUST The roller rockers?

sorry to highjack this thread,but was wondering if this could be used(1.8 rollers)with my TR224/112 cam with 918springs and what would the typically(if any)gains be if used on this cam.

As mrr23 pointed, the CRANE/Vinci rockers are better than slp rockers which are just stockers in a different ratio.
The accelerated lift tech that Crane developped has not been matched by anyone yet.
Kit comes with everything including p-rods.
Setting preload and lash is a bit tricky but there is good install info on the VINCI site.

aight. but the only thing is i only need the roller rockers... not anything else cuz i already bought the other stuff.
would crane/vinci sell just the rockers if i contacted them or something?

yes, you can buy just the rockers and poly locks. you will have to get the appropriate length pushrods as they require shorter pushrods. also, because these are adjustable, you have to have the guideplates.
now, what if i keep the stock 1.7 ratio and get roller rockers? will that change the length of the pushrods, as the stock ratio is 1.7
if not oh well, cuz i sure as hell aren't takin out what i got to just have it set around and have to sell it

even if i convert to the crane 1.7 roller rockers, which is the stock ratio ; i would still have to switch, but i wouldn't have to switch at all for the HS YT or SLP ones.
i have heard about the yellow terra rockers. but since i'm not taking apart my springs and locks again, then whats the best bet? HS or YT?

ok, learned that Harland sharps' break after time/wear out (heard from people) due to weight of Yella terras and inertia they cause valve float; Vincis are 800bucks, jesels are 1300 bucks.
I'm seeing that the stock rocker is plenty good on my car for all that i need. I don't plan on building a race engine and spending a lot of money on my car; so yeh. def not seeing roller rockers in my future

My only point was that if anyone upgrades to higher ratio rockers they need to upgrade the springs. 
They barely control the stock cams.I have the Crane 1.8's with a 228-230/571-573 112* cam. I've got maybe a 1000 miles on the setup. But I must say that the Crane's are a very nice rocker. For the money it's not a bad deal. They come with the guideplates and 7.250 pushrods in the kit. In my setup they are fairly quiet as well. I don't have hardly any valvetrain noise at all. I don't have any experience with ant other rocker though, other than stock.
Another wise option is to just get your stock rockers rebuilt. I think it's Nasty Performance that has them rebuilt by Harland Sharp. They press out the old rollers and put in sealed units. It's not bad and alot of people run them for I think around $250. At least with this option you don't have to worry about puking needle bearings from a stock rocker.
