Hey,
I have recently began porting out my 202 head to use for hillclimbing and am now deciding on what valves to go for as i want it to produce as much power from it as possible, i have seen that some people use 1275 ones, but which ones do i go for.
I will also probably install unleaded hardened seats but am also unsure on what ones to go for and where to buy them from.
Also what would be the best combustion chamber design for these particular valves.
Any useful information that may help would be much appreciated.

Cheers
Sav

I would invest in Vizard's yellow bible. It has where to port, what chamber shapes to make etc in it. Well worth the read. Most A-series mini owners would have a copy of it stashed away somewhere.
