If that's the case you'd expect the valves to have been reground already, so it may be something simple like head gaskets or valve clearances. Fingers crossed! You'll know more when you pull the intake manifold off.

What are the chances this engine has adjustable lifters? Is that a "mandatory" thing to install on a rebuild?
