Currently have the k20a3. Was wondering what I can get out of swapping the head. Can I do the work myself? Pricing? Benefits? Or should I just leave it stock.

You can swap to a k20a2 head. The more aggressive cams in say a k24a2 head won't work with the stock a3 pistons.

What you can expect is 170-180 whp with kpro or aem ems.
You can do it yourself if you know the engine. It's not complicated but if you don't build engines i wouldn't tackle it without a helms manual or something similar.

Honestly, better results have been seen with vtec killer setups on an a3. 02-04 rsx-s cams, rbc intake manifold, exhaust,and kpro tuned have netted 190+whp

Price wise, vtec killer is cheaper. An a2 head pricing varies when buying second hand.

I don't understand what the vtec killer is
With the k20a3, a vtec killer setup has the rsx-s cams running on the high cam lobe at all times. Thus removing the vtec crossover in normal operation because it's always on the high lobe. That's where the name vtec killer came from.
