TR 250 Cam and Rocker Upgrage

[Kenneth Brown <kbrown@trmx3.dot.ca.gov>]

I'm in the process having the head rebuilt for my 1968 TR250 and am wonder if I
should upgrade the cam. I don't plan on racing but do enjoy spirited driving
around the country roads. If I do upgrade am I just opening up a can of worms
with idling, timing, emissions (Calif. car) problems etc. Also is it worth the
money installing roller rockers. I would like to do it once and do it right.

Thanks,
