34/34 weber, 24/27 chokes, 150/150 mains with 170 air correctors.
camtech 609 regrind, shave rocker towers 2.5mm, dual valve springs (like from www.performancesprings.com.au)
3K bigport head, or a stock 3K head (free 10:1 CR)
port the exhaust 1.5-2mm on walls and roof of port, make intakes about 30mm diameter (bigport has 30's stock, normal 3K has 27mm stock)
unshroud valves in combustion chamber, smooth sharp edges.
NGK BP6ES (or Y) plugs
ACL 40 or 60 thou OS pistons (don't use the Repcos, they crack)
balance rods (end for end and total) to 0.1 grams. balance pistons and pins to 0.1 grams, balance crank dynamically.
4-2-1 extractors, primary and secondary 1.25 feet long, 2.5 foot collector into 2" exhaust a couple of resonators and a big NON-straight thru muffler.....
this will be noticeably better than stock, and will put down around 47-48rwkw@8000rpm on Toymods dyno...
much more fun and if balanced properly etc, will rev all day to 7000rpm.....
use mobil 1 or similar synthetic oil and change regularly, and motor should last a while too....
can bore 4K out to 60 thou over (1.5mm) but much more is anyones guess. you can bore a 3K out 3 or maybe 4mm, but 4K has thinner bore walls.
if you are after real performance, go the 4AG etc, but if you are after some cheap expendable fun that will scare afew commondores, then the above mods should be ok..
Cya, Stewart
