I'm about to do the same on my '73 Clubman. I want a basically standard

the ports and fitting hardened valve seats and maybe oversize valves if
they
need replacing, extractors and a 1 1/2" SU with bigger needle/jet. Any
thoughts on this?

valve seats good = unleaded fuel

dont bother with the port-polishing.

get a *good* exhaust system; i like the RC-40 with a maniflow manifold
(headers in US?)
use the smallest bore system you can find, if its a stanndard
head/cam/valve size

you will need a separate intake manifold.

finish it with a diffrent needle to make this modification work.

have a look here:

Thanks, Keith, that is what I had in mind. Any idea which needle and jet
they use in the stage 1 kit?

Graham


Get on to Fabre in Sydney 02 97581966 - they can sort you a needle -
just tell them what you have done - very little difference in the
jetting with what you propose. BTW they also keep mini parts to OHaul
your motor.

if you look down through the link i sent you to Minispares, the needle
they reccomend is AAU, which is a nice flat profile. (richer than
standard at top end, where the exhaust mods really come in to play)
