Switching to roller rocker arms
Hi,
While changing my heads, I had my engine switched to roller rocker arms. Can you please tell me what are the consequences? Should I feel a difference in the driving? Does it require a change of cam? Can it explain some misfire?
Thanks!

It should be beneficial. You won't notice any gains unless you went to a 1.7 ratio. You may not even feel that. If you have a misfire, recheck your valve lash. You may have the rockers adjusted too tight.

Thanks!
Just to clarify, by misfire I mean bad throttle response (or no quick response at all when I double clutch for example). But, when it is running, it pulls very hard!
How hard is it to have the rockers adjusted?

make sure the cam lobe is all the way down, then adjust the rocker arm nut until there is zero lash in the pushrod (wiggle/spin pushrod while slowly tightening the nut until the slack is gone) and go another 1/2 turn.
the roller rockers should free up a few HP, and be easier on your valvetrain. did you replace your pushrods with hardened ones? if not the guideplates will eat into them.
