Make sure the distributor advance weight setup is not rusted solid. I have worked on two different Bobcat loaders with V4 Wisconsin engines that would split the aluminum heads.
In both cases, the distributor was rusted up from storing the machine in damp cattle barns.
The odd thing is that a Wisconsin V4 with the distributor advance stuck in the full advance position, will start and run normally, but under heavy load at low rpm, will spark knock bad enough to crack those aluminum heads right between two cooling fins.
A quick test for a sticky / stuck advance, is to grab the distributor rotor and twist it in the direction of normal rotation. You should be able to twist it about 15 degrees against light spring pressure, and should snap back to the original position when released. If it won't do this, the distributor advance is sticky / stuck. Remember to put a few drops of motor oil per year on the felt pad in the end of the hollow rotor shaft to keep it lubed.
This is where the most advance sticking happens because no one remembers to oil that little felt oil wick.
