You need to have a cam that works with the ratio rockers. I believe the scat C35 is for 1:1 stock rockers. The 1.25's are for getting more lift from a STOCK cam. If you use them with anything else you can get the valve wear you are getting.
 You will need new valve guides and springs at a minimum.

Oh yeah, forgot to answer the question. Yes, ratio rockers can add HP, but to get longevity, they must be set-up correctly.

My mechanic had said that I needed 1.25. However the cam size you referenced seems very familiar. Thanks for the reply. I'll have to double check my original spec sheet to verify my stated cam size. Any further suggestions are appreciated.
Just wondering, how much more horse power could one gain with rocker upgrades (if done correctly)

Well, about 5 to 10% hp depending on set-up. In the build spec sheet on your first post it said you have a C35, this has slightly less lift and duration compared to a engle 110 cam. (which is used with stock rocker ratio)
