Comp Pro Mag 1.75 roller rockers
Comp Pro Mag 1.75 roller rockers I was thinking about getting these roller rockers, but couldn't find any feedback on them. Do you guys recommend them? It would change my lift from .585/.588 to .602/.605. Will I notice any difference?
Thanks

I had a problem with valve float when I used them on a previous setup.
Now, in all honesty with valve float you can not always blame rockers. But, after posting the dyno graph (~3-4 years ago) on this forum..a lot of members advised going back to the stock rockers. Apparently stockers are one of the 'lightest' as far as weight over the valve.
I chose to just make my lift via the cam profile vs a different rocker on my current setup..I think if you look on the fine print on a lot of cam lobes/profile cards, you will see the advice concerning rocker ratios..especially the XE-R lobes. They are very careful in their 'advice'.
Again, can not 'prove' those Rockers were the problem, but you asked and I just honestly told you my prior experience.
Good luck either way.

I run a set and have had no problems. Advantages are adjustability, reliable fulcrum bearings, less parasitic loss. The stockers are known to shed needle bearings. You should run hardened pushrods with the Comp guide plates. A rub against the Comp setup that I have heard is that the adjustment nuts loosen
I installed a set of 1.85s nearly ten years ago. I did have one set screw loosen up about 3 years ago, but I was close to home when it happened so it worked out OK. I would put a little locktite on the set screw threads and you should be all right.
are you just trying to increase lift, or are you wanting better rockers or what?
My preference would be stockers with fulcrum upgrade. This locks the needle bearings in, as well as puts a lock ring on there for good measure.
