Can I install my 1.6 roller rockers in wrong....
I just did a few mods to my trans am and I feel like its slower than it was.....
The roller rockers are the only thing that make me worry....

 

Not enough details...

 

Yes
A number of things....too much preload when you tightened them down would be the #1 thing..... Used NSA rockers with no guide plates and now the rockers are crooked over and off the valve stem. Or used SA rockers and the SA tabs hit the retainer and popped off a few springs.... valve train geometry is off..... lots of things, its not just a bolt on part if you don't know exactly what you are doing.

Need more info as mentioned by sb.

 

To add to what has been said above, you also won't feel any difference with just the 1.6 rr upgrade even assuming you installed them properly.

 

Yea, I didnt expect to feel a gain in power just yet, I added. 1.6 roller rockers, hardened pushrods, LT headers to a ORY with glasspack, went from 2.73 to 3.42's and also did a TH350 swap....

 

your going to have to pull the valve covers and verify that the valves are set correctly, however someone correct me if im wrong but the lack of performance your speaking of could be due to the different first gear ratio of a 4l60 to a th350.

 

Did you change the valve springs? If not, you probably should have.

 

a tune probably wouldnt hurt either

 

I have new valve springs but I never put them on.... didnt think it needed them until i put the cam in....

 

Most people would recommend you put in new springs with 1.6 rockers, just to be on the safe side.
