Did you ever fix the problem you had with the head? Wasn't it warped or some shit? I can't quite remember...
So good luck with the build. Personally, I wouldn't do it, but then again I'll be 30 next year. Your still a young single lad and can fuck with this stuff.
I think if it were not for you doing all the work it could become quite costly.
www.speed-garage.com may be a good place to pick up some internals. They may put together a package deal for you as well. Ask for Uriah, if he still owns the joint he is the one to talk to. Just tell him some guy named Ron who use to be in the Army who purchased a zc and b16a motor referred you. It has been a few yrs. that may ring a bell.
