Oh jeez I just realized you're Gary from Design Craft. Well if anyone can it should be you 
VTC for sure would be an advantage, I just think nobody on here has tried it yet because most people aren't full on road racers and this would be something that would involve a lot of custom work, time, and money.
I think the easiest way to make this work would be to get a K20 head on the F20 block. If there was a way to modify the F20 head to use the VTC system that would be nice but due to things lining up and space I just don't see it possible.
I know there is a build out there with a H22 block and K20 head, and given the similarities between the F20 and H22 block it should be possible. Using a modified K timing chain (I believe the K deck height is taller), crankshaft, and k20 head it should be possible.
Some of my random thoughts:
- This wouldn't be worth it unless you made a custom intake manifold or could get the S2000 IM to bolt onto the K head.
- You would want head work and larger valves in the K head as they are smaller than the F20 head
- A lot more aftermarket cam choices with the K series head
- Would want to use the K20A head as it has 3 cam lobes on intake and exhaust.
- The K series and F series head gasket are the same part number
If you wanna assemble my F24C block you can borrow it for research LOL

Having played with cam gears quite a bit, I don't think having variable cam timing on the intake would be very advantageous considering the cost to get a system working. I certainly wouldn't buy a system.

hahaha. thank for the compliment and the great info. I started this thread for two reasons. one, to see if anyone has an s2000 with iVTEC and two, see if s2000 owners wanted it. Believe it or not, I think i got it to work on an S2000. it took a few months but we'll see if it fires up in the next few weeks. oh and btw the F and K head gaskets are different. sucks

The F20 and K20 head gaskets are not the same.
They have the same bore/bolt positions but different shaped outer periphery on the block. It would run but would not hold water or oil.
Better option would be to use a custom adapter plate to fit a K20 or K24 up to a F20 gearbox. That way you run stock K series head/block setup.
I've tuned k24 and K20 motors with VTC. Very nice how you can move the inlet camshaft advance on the fly to stretch out the power band. Also, they idle like a pussy.
As far as the question goes, It would be possible to put a K20 head on a F20 block and get it running if you tried hard enough. This would probably involve a completely custom timing chain setup, covers, external oil taps for the VTC oil feeds and a lot of welding of the head so it would seal up with the F20 block. It really depends on how much you want to try.
On the other hand a k20 or K24 transplant would be a comparatively simple task and easily transferable to another K20 after a blow up.
