Default upgrading the head

I have a 02 rsx-s and I just bought cams,valves,valve springs and retainers, k-pro . I was woundering what I could do to the head to succesfully make 400hp with turbo and fuel upgrades.
I'm attacking the head first then the block, piston, rods,sleeves, and balanced crank. Easier on the pocket.

What did you actually purchase, and what is already installed in your car?

You don't even need to touch the head to make that kind of power.

the lobes on the cams are 520 insted of 486, everything else is just to support the extra preasure.
so u are saying that I didn't even need that?

Pretty much. There are guys squeezing 600 whp on bone stock K20 motors.

Start on the bottom end. I would upgrade the pistons and rods just for piece of mind. Just get a good tune and you will make the power reliably.

What size turbo are you looking at?

400whp with a good tune should be easally done on stock motor with a good turbo kit and atleast 3in ex.
