one side of engine hotter than the other

hello experts...any ideas on why one side of engine would be hotter than the other after a brief warmup?...1998 boomerang...thx

When you say the side of the engine, are using an infrared thermometer on the block or using your hand. Or are you talking about the risers?

plugged waterline feeding the exhaust manifold?

as ga indicated, need more info, but that would be my first assumption. should be drains on the bottom of the manifolds. drain them both and see if there's water in each one.
