I have a 2200 cavy , I want to install 1.6 RR . I know Crane and gm performance make them for the cavy , I remember someone saying that summitt made a set but I dont have the part number. If someone can give it to me or let me know if there is another company to go through . I am new to the 4cyl game and cant justify spending $300 when I bought roller rockers for my 97 trans am and paid $20 less for 16 . Thanx
Comp Cams makes them for the LN2, you can buy them through J-body performance. I don't know about Summit but this is a reliable place to purchase them:
JBP - 1.6:1 Magnum Roller Rockers (LN2)

your stock 2200 rockers are better than those. the crane rockers have a better bearing set up and are closer matched to the 2200
I thought the 2200 already had roller rockers from the factory??

They do..he wants aftermarket ones.

The magnum 1.6:1 are better then stock man ....... they are made of better material etc...... they are a cheap alternative to get the 1.6 lift and still have a reliable STOCK replacement.........................
THEY ARE A STOCK REPLACEMENT THOUGH..... thats why they are only like 149 bucks...
haha

As Phlatcav already said, the Magnum rockers only have a roller fulcrum (which accomplishes next to nothing, whereas the stock 2200 rockers already have a roller pivot, which is the important part.
Now, to save Madjack a post, the Magnum rockers will be more accurate than factory, but probably not worth losing the roller pivot. The Magnums are a good upgrade for the pre-98 2.2L, but for the 2200 the Cranes are the only way to go.

That's the "roller fulcrum."
The magnum rockers are ball fulcrum and roller tip.
And this leads directly into a thought I've been pondering over the last few days. Frictional gains vs VE increases:
I don't know if I've ever seen anything in print showing or estimating power gain at the crank after switching from ball fulcrum to roller fulcrum rockers. Ball type are found on the 2.2 OHV and roller type are found on the 2200. Almost all swaps I've seen also include a ratio change.
For an engine I'm currently building, dyno software (FWIW) is predicting about a 2% increase in power with a switch from stock 1.5 to 1.6 ratio (non roller) rockers. I'm thinking that roller fulcrum 1.5's would do as much or more for the power. Any thoughts? Anyone?
And yes, I've blatantly jacked a thread.
But there is a part number for the crane narrow body 1.6 rockers in the 2.0L OHV buildup guide. The number is still good last time I checked.

Ah crap, I was thinking the 'fulcrum' was the tip.
Everyone, please ignore my last post on the account that I'm an idiot

The reduced friction does, in theory, free up some horsepower, but I'm not sure how much. It's sort of like lightened pulleys and such. They don't actually make more power, just take less. The actual power gain is going to be due to the increased lift. I've heard there's a very slight increase in duration because of increased travel, but I doubt it's enough to make a difference. The actual numbers I believe are 10-15 HP at the crank, but somehow I find that hard to believe. Maybe with a cam upgrade, but not just rockers. I could be wrong.

ya but with a cam upgrade you then need pushrods, and lifters....... stock lifters= bye bye with a new cam .

Springs, retainers, bla bla bla... Yeah, and at that point you might as well do a P&P just to make it worth the trouble.

^^^^^^^^^^^^ true ... if you take OFF the head....... might aswell ARP the @!#$ out of it too ..... and a cosmetic head gasket ..... haha MIGHT AS WELL

^^^ i was about to
as well! But Ive done the same thing before so oh well
Far as stock lifters with a cam I think youd be ok long as ya replace them with new ones. There are not a lot of options for upgading 2200 lifters
New OE would be fine but if you use high lift rockers AND a more aggressive cam, you'd need stiffer valve springs because the stock ones won't handle the stress. Pushrods are a matter of luck, I think. I've talked to some who use OE replacements and they work fine, some swear by them, others use chromoly pieces and wouldn't recommend anything less. I personally wouldn't trust the stock ones, but I'm in the same boat here. This is my first pushrod engine. Until I got this Cavy, every engine I've ever worked on was DOHC, it was never an issue.

Howell Automotive sells a set of Crane Roller Rockers, and new studs. All you'll need to put them on a 2200.

whoops, completely missed where Madjack already posted this

why do you think stock springs wont handle higher lift?
Phlatcav wrote:why do you think stock springs wont handle higher lift?
You can only compress any spring so far before it binds. A higher rate spring can safely be compressed further.
I think the stockers are fine for new roller rockers, but if you add a cam to that you should probably look towards new springs. However, you also have to remember that increased spring rates and higher ratio rockers increase the load on the hydraulic lifters, which can only take so much

If hydraulic lifters can't take it, just get solid roller lifters. I'm sure with enough parts scrounging, a set of solid lifters that fits could be found.
And its not like adjusting the valves on a 2.2/2200 is that difficult, about a hours worth of work at most, and that includes a beer break.

Harder than you think. The only known good set is no longer in production. Any others would have to be modified by a machine shop. JBP does offer HD lifters with an upgraded plunger however, those will be what I'm using.

what is a good set of stock replacement 2200 springs that will use oem keepers and retainers
kinda random but how much would it cost for someone to get these on and adjusted from a professional?
