340 heads or gasket leaking?

Hello,

I have a 73 340 installed in my 65 dart. It is a low compression motor .030 rebuilt with headers, airgap intake and a 242/248 cam. The heads are from an earlier 340 with 2.02 intake valves and little porting (got a good deal on them).

I did a compression test and all the cylinders are all in the 130-135 psi range with very little variation.

The motor runs good, no issues other than condensate coming out of one of the pipe. There is no H or X connectors, each bank runs independently to the back.

So, when the engine is at the operating temperature there is a quite a bit of water coming out of one of the tailpipe but not the other. First time I thought it is just condensate, but when the engine is hot.....????
There is no contamination of the oil or coolant whatsoever.

What can it be? Is it normal?

Thank you.

How much and how long does it come out. With manifolds and a working heat riser, you won't get much from the passenger side when started cold. Condensation will build up in the exhaust and settle in the mufflers. Once the pressure get's to it it will spit out of the tail pipe until the engine warms it up. If enough is in there it will turn to vapor which just looks like exhaust smoke. Is it using coolant. If you don't have to keep adding coolant it is probably just condensation.
