Default More Power Without Going Inside

Hi All,
I don't want to put a cam in my 1998 ls-1 and have done everything else I could (335)RWHP. I was told that I could get another 20-25 hp by changing rockers. What brand is recommended and what ratio?
Thanks,
Mike

Name what you have done, 20-25 is a tad high for just rockers.

Plus I would think you could get a little more than 335 with a new intake and headers with a good tune. But then again if its an auto those are pretty decent numbers.

I think SLP and/or Comp Cams have 1.85:1 ratio

It would not be more power but you could go with a higher numerical rear gear ratio. A new rocker ratio will help, but I don't know how much it is worth on a stock cam.
