H22 header and intake manifold


I got my 99 civic hatch with a h22 running. Only had it for a couple of weeks but I already want to start fixing it up. I'm looking at buying a header next month. Maybe an an-r, header tech, or bisimoto header. Does anyone have experienc with different headers on h22? I saw a dyno for the dc sport and it only put down 2 hp so I'm looking for a bit more.

Also I want to get an intake manifold while I'm at it. I'm going to use the hondata gasket but which mani should I get. I have been waiting for skunk to release theres for a while. Does anyone know what has to be done to the Euro R intake to fit and what hp numbers I might get? thanks alot.
