Did you have the engine block checked? Be a shame to put a known good head on a warped or cracked block.
Hopefully that's not the problem..
*I've read something about the water pump or timing cover? leaking coolant, but I don't think it was making it into the exhaust..
*Are you certain it's coolant and not just normal water from condensation in your exhaust pipes? Hope that's what it ends up being.

I don't think it's condensation,because i had to add more coolant.I don't think the block is cracked,cause there's no oil in water or water in the oil.Also the temp rises quickly. thanks

Well, I didn't mean oil to coolant leak. I was thinking a leak from the water jacket directly to a cylinder. It wouldn't necessarily get into the oil that way, but I'd think your coolant would have evidence of exhaust gasses in it and heat up quickly as you stated. I'd look at the plugs. Burnt coolant makes 'em look funny. In any case, keep us posted what you find out.
