yea, right now, i would call whoever you bought it from, and have them give you the information they better have on your block. otherwise you are up shits creek.

i mean hell, you still havent even told us what the motor is...B16a what?!
and nothing about the "build" is out of the ordinary.

the only thing i could say that you might have a chance of finding, is the cracked header...they might try selling that...personally i would toss it, because its not an ordinary part...if it was fine, like any other header, then yea i'd sell it. what you need to look for is someone selling their stock motor because they have a new b16 swap going in. chances are these people arent selling it, they will be putting it into their own cars.
