Or just go l20 be stroker with either z22 or z24 crank and run twin 45 or 48 mm Webers, should be good enough for between 150 to 200 hp that will be plenty in a 1200, that's what's going in my ute, I have the one being built for my 1600 at the moment :)

If you want to be different, go an SR20VE and quad throttles. Will make for more power than a KA head l series. Will have standard reliability and will be lighter.

Plenty of info on VE head swaps these days

I can put an L SERIES in legaly without too much hassle. If the ka head gets too hard ill gi L head but I do want something a little different

Not many of us are interested in doing that.

But where I live KA is the engine of choice for Datsun swaps.

Using the 3 valve head is much easier. I can get navara 3 valve heads. Wanted to kno also what my compression ratio will be if I use a stock ka24e head on a stock series 2 bluebird (910) bottom end? I dont think it will make the 10-10.5:1 compression ratio I wanted. Can I use any other piston or rod and piston combination? Im getting into not so familiar territory but hey this is what its all about isn't it?

KA head stock with stock cams makes as much power as a heavily ported L-series head with built cam.

Fit an import KA20DE, a good used Japan motor. Just as easy as a L20B swap, much easier than swapping heads. And legal too. Swaps easily onto a 1200. The DE (16 valve) makes significantly more power than the E (12-valve), at a higher rpm. Rev it up!

I rhink the 3 valve head is an easier fit. Not sure if the valves clear with a L16/18 but does a L20b. Can also still run carbs

i can understand your position, good luck with the build. It would be really good if you could write a build thread on the KA head conversion. I am interested as to how difficult or easy it is compared to what i have read.

Your in sa, speak to dats port por maddat. They should know how to set it up.

Yes but I want to be different
