OK, I'll pipe in with a few boneheaded questions, I'm a rookie, so
please go easy on me....
I'll first say that I understand completely the motive of vintage racing
to keep things in accordance with period technology and I wholeheartedly
agree with that. However, I'm a little troubled by the roller rocker
issue.
It seems that the overall benefit of roller rockers has more to do with
valvetrain reliability and longevity than performance. Am I wrong?
It also seems that with all of the things you can do to cheat (and I saw
several obvious ones at the Sears Point CSRG event) that roller rockers
are one of the more benign. If I could, I'd run rollers just to spare
the valvetrain additional wear and reduce the possibility of failure.
Should we also outlaw synthetic lubricants? Should we make everyone run
on bias-ply tires? Should urethane and nylatron bushings be outlawed?
What about breakerless ignitions?
I don't mean to entirely impune the no rollers rule, but I guess I'm
seeking a better understanding of why the rule is still in existence for
many groups.

'67 MGBGT still in pieces waiting for paint - but no rollers, honest.
