cooling problems

hello I have a problem. I have a sixty four and a half mustang that i put a 66 289 in. I just changed out the intake to a rpm preformer and the carb gaskets leaked some where and i got alot of gas in the intake causing a huge back fire. well i got the car running and now im getting water aot my exhaust. I've done at least 8 other intakes dose any one have any ideas?

Water out the exhaust sounds like a blown head gasket.

water out of the exhaust is a perfectly normal occurance. Its probably just condensation coming out. If you do suspect that you have a bad head gasket, go to the local auto parts store and buy a cylinder leak down tester. hook it up to all 8 spark plug bores and look for bubbles coming up in your radiator

How much water are you talking? A drop now and then is fine anything else or steam is to much.
