Yeah I've herd there's only about 9mm or so of meat in the head so chances are you'll drill into the oil way no matter what.

Yeah I've heard a thread sealer works, I think Devil Developments press stainless steel inserts into the head and then tap them, though for the power you're after I think that's a little OTT.
Even then I'd say you'd be better off going for a tubular jobbie.
Good luck with it mate.
