My 1989 Prostart 351 Ford overheated last weekend as I pulled it to the dock. It ran fine all day 4 hours (17 miles down the lake and back) 140 to 160 degrees. Why idling at the dock the meter sounded. I turned off engine, tried to restart a few minutes later. Engine would not crank. The next day at home I tried to turn the engine over; nothing. I finally pulled a few plugs and found water in the cylinders.

I have checked the intake manifold and heads finding nothing (visually). I have sent the heads out to be checked. If the heads are fine the next place is the exhaust manifolds and risers. Correct? Is there an easy way to pressure check the manifold and riser?

Any best next steps?

Thanks for any information.

I doubt the exhaust manifolds caused the water in cylinders issue. Most likely, it's either a head/intake manifold gasket or a crack. While the heads are at the shop, have them Magna-fluxed. If you look online, possibly at SkiDim, you may see the setup for checking the exhaust manifolds.
