I have roller rockers fitted, over 4 years ago.
I cant say it has made the engine any quieter - possibly a tad louder on valve clatter but nothing overly concerning.
Performance differnce post fitting is noticable - it is more free revving , on acceleration the revs just shoot up as far as you want with no hesitation.
This was with Morgan stage 2 exhausts which were already fitted , and I get the same with the G56 pipes currently fitted.
It did have an ECU tune up on a rolling road at the time post fitting , which may have helped , no idea how much though.
