A6 header fit zc?
I'm running the dc sports header on my a6, and I'm considering a swap to a dohc zc. I'm also wondering what other things, if any, will need to be done for this to drop into my crx si. Also, will i need a zc hood or another similar?
If it's going to be too much, I'll just swap in a sohc zc.(I know its the same motor, but it's a whole lot fresher than mine is and i don't have the downtime to rebuild mine)

Yes. The ports don't line up 100% perfectly (they're about 1/8" off), but it's close enough and the bolt-pattern is the same. You can do some port work on the header (not on the head - header ports should be larger than head ports for anti-reversion purposes) with a Dremel to match them up closer.

You have to switch 2 wires (blue with a yellow stripe and blue with a green stripe) from the distributor plug to the cylinder position sensor on the end of the ZC exhaust cam. That's it. Everything else plugs/bolts right up. I would highly recommend picking up a PM7 ECU if you don't buy one with the engine. A PG7 will also work. The PM6 is not really ideal.
You'll want to do major maintenance jobs (specifically rear main seal, clutch & pressure plate, resurface flywheel, release & pilot bearings, transmission input shaft bearing, timing belt/tensioner & water pump, etc.) while the engine is still out of the car. The DOHC ZC parts reference list can be found here.
