I will leave the debate as to whether or not there is any performance gains by going with roller rockers vs. the stamped OEM to others.

I will add that it is my understanding that the OEM may vary as to their true ratio. Perhaps this is due to manufacturing/quality control or wear over time etc. I seem to recall that they tend to vary and are oftentimes found to be <1.5.

The other consideration you may need to look at if you end up going with a roller rockers is the need to purchase a spacer kit as well. This cost additional $$ if that's a factor.

Good luck and hope you achieve the desired affects.

I believe if you go back to my post you will see that I credited any improvement if any to a more accurate ratio. I had Cranes and they came with the spacers. I also stated to find the noise problem first and recommended a doctile iron adjustable set instead of the rollers if a truer ratio and adjustables is what you want. On the street you will never notice a performance difference. But again it is up to you, it is your car.
