hey,

do you have a GSR (Sir-G) or Type R? on your head it will say P72 for GSR and PR3 for B16/B18C. All honda cars with vtec (type r, del sol vtec, 99-00 si) they all use the same PR3 with slight variations (lma's, cams, valve springs) the type r head has a slight port/polish from the factory.

so to answer ur question, yes!

You will lose a bit of compression by switching to the PR3 head, but it will bolt right up. You will need an intake manifold designed for a PR3 head though.
