...If they are non-self aligning rocker arms, I hope the push rods you ordered are the HARDENED push rods.
Are those "stamped rockers" self-aligning or not?
What comes with the "kit"?
It won't hurt to preplace the push rods, what length RP did you order?

On this kind of upgrade on a 1989 motor all you need is FULL roller rockers and LT4 springs. You can get full aluminum RR's from a reputable supplier for about $230. You can get LT4 springs from GMPP for $30. You don't need new pushrods. Spend the money on the things that have the most impact. Buying roller tip only stamped RR's and hardened pushrods is a waste of time and money IMO.

Since vetteman8924 never would say, I went to the trouble to check out the rocker arms. They ARE self aligning. It appears the "kit" is the rocker arms and the (unneeded) push rods. The unnecessary push rods won't hurt a thing, but unless he knows he has problems with the existing push rods, they were a needless expense. Hopefully he won't have to buy yet another set, to correct any geometry problems. The GOOD news is that they are the self aligning rockers and he doesn't need to buy anything else to "adapt" them.
Not really. The bearings (rollers) DO reduce the friction, but especially for this application they would show no increase in performance. In fact for $100.00 less than he spent, he could have bought plain, stamped steel rockers, without the roller tip.

The title of the thread indicates he wants 1.6 roller rockers not a replacement for what he already has.

When I did my setup I Summit had a delay so I ordered from CC direct and had parts the next day.

The '88 uses the 128 heads, doesn't it? Those heads should have non-self aligning rockers with "real" guide plates and hardened push rods, stock. All they should require is the new, non-self aligning replacement rockers. All the 1989, 113, heads would need is a set of self aligning rockers or, if changing over, the plates and rods as I outlined above.

If you want to spend the rest of the day parsing my words go ahead, but I have been consistent with my answers regarding how I would approach the original question.
Have a nice day!

Your false accusations are only a weak attempt to draw the attention from your deficient postings.

Your postings are going far beyond simple hubris. I love YOUR statement that I didn't write what I was thinking. Either you consider yourself God like, or this is simply the ranting of a madman. How could you possibly know what I was thinking if I didn't say it.
I know things can seem vague if you don't understand the context of a statement. That is not my shortcoming but yours. I think you are just being mean and arguementative because that is your nature.
As usual you don't see that as a problem.

hi everyone im new here and have a question to ask i have a 1989 vette stock automatic i was thinking about ordering the 1.6 stamped roller rockers from summit but was not sure about beig able to run them? any help would be great!! also if you can run then what kinda of power am i looking at?
Yes, you can run them as long as they are meant for your 89 valvetrain setup. Years ago I had a problem running stamped, 1.6s on my 86E because the pushrods would bind against the slots in the iron heads that engine came with. I ended up with half a dozen or so bent pushrods.
My point is, make sure the rockers you're considering are designed for the heads you're running.
You may see an increase in power because of the additional valve lift and slight increase in camshaft duration you'll get with the 1.6s. I have to emphasize MAY, because I've never seen back to back dyno results on them.
Hope this helps.

Just to muddle the waters further , the 128's on my '87 heads were SA.
I was of the belief that all the alum head, roller cam L98's were SA.
As stated above;
regardless of what style (roller tip or full roller) you go with;
if you have SA ,you only need to buy SA rockers .
If you decide to buy NSA, you need guideplates and new pushrods

Another wrinkle to this whole thing is that CompCams recommends that for a high performance (or some such wording) application, go with NON-self aligning rockers, guide plates and hardened pushrods.
I found it buried in some of their literature.
The problem now becomes, how do you define "high performance" or some such wording?
Now that I've recalled that info, I'm now NOT getting the CompCams 1.6SELF-aligning rockers for my LT1 but will, instead get their 1.65 NON-self aligning rockers, plates and rods.
Anyone have any experience with those?
