must be a dog of a 4age if your 4ac can stay with it, standard 4age is 86kw standard 4ac 57kw. Dont know what kinda results these would yield on a 4ac haven't had the cash to waste saving everthing for the 20v half cut  IRA11Y? I was thinkin it might bump power to 65ish kw??
As for more power with out putting a GZE or 20v in then umm 2" exhaust and dril some holes in the standard air cleaner run some pvc down pipe to it like a cool air intake. might gain a Kw or 2 it'll at least sound a lot faster

Ive got a couple of 4AC dizzys here you can pick what one you want $50 each.
Hmm Im not sure what you mean Hunty? are you planning on using a 20V bottom end??? you may want to consider changing the piston...although it would be possible to set the timing at the cams so that the valves closed a little earlier and there-by had no chance of hitting the piston (unless the cam belt breaks as using the GE block with the C head no longers means a no interferance system) it may be better to get some pistons made up..if you got forgies then you could boost it as well..for no other reason than because you can! before everyone jumps in!! just make sure you get them made with the right size gudgeon pin to suit the block you want to run.
Elmo, where did you get your extractors made and how much did they cost?. you could try running a bigger carb like a 32/36 weber or better still but probhably overkill is the 36/36 IDF, youve allready got the extractors so it will be easier to fabricate something to fit the bigger carb.

Sorry it was a late night post - not very clear -
i was just asking if you thought the mods he had to do the 4AC engine ie. port polish, head shave and cam ect would give much performance gains i was thinkin it might push power output to 65ish Kw ?? Because these engines have the inlet manifold sitting ontop of the exhaust manifold doesnt this really limit their potential?
About the 20 Valve, im saving up to buy a half cut and then drop everything i can out of the front cut into my AE82 not looking to make some weird 20valve 4ac hybrid, as far as im concerned the 4ac will do its best job as a boat anchor
