122 Upgrades 120-130 1967

Does bolting a stock B20F head on count as internal work? :^)

I think with 8.7:1 CR you could run pretty decent boost levels. Although you have to be more careful of preignition with a steel head - aluminum heads, I guess, prevent hot spots better.

KGTrimning sells special 'Turbo' heads with 7.5 - 8:1 CR and big exhaust valves.
