I'm building a 403 bored to 4.75 with 4231 heads. Got everything back from the machine shop and put it together.
First start thought everything was good, but after a couple seconds I was getting water out the exhaust.
First thought was a head gasket problem. Got a new set of head gaskets off of Welters (they confirmed they were the right ones for the block/head combo)
Got them put on last night. Every thing went back together well. Used copper coat this time on the gaskets too for extra insurance. ....... Exact same problem.
So I have:
Good compression
No water in the oil
No bubbles in the radiator
A good sounding/running engine
Water getting into the cylinders (appears to be all 4, some maybe worse than others)
It definitely sucks water in when you open up the throttle. It's way worse after giving it some throttle.
Machine shop said to bring the heads back to them. First thing they will do is a pressure check.
I'm looking for advice on if there is a common place to look for problems like this.
Thanks!
