I'm wanting to build my 2001 accord f23 ulev.

I know my head is garbage for power and I've heard the h22 head off the prelude will be a start, but I want to get into the 500whp range and I'm not sure if I want to go na or fi. Which do you think will be the best setup? I'd like to keep the original block, different intern als are ok.

Note: Im a tech at a local shop and all the labor I will do myself except maching.
