It's a '89 Civic HB. That's all I really know about it. I'm pretty sure it's just a 1.5L, but the person said it had a different head on it, so I just want to make sure what I got.

Give a call to one of the machine shops that does heads. They should have a book that has the breakdown on the head nums...
