Case 930 Head

Still having trouble with my 1967 930 diesel overheating when pulling hard. Will be pulling heads and hoping it is just the gaskets. Any advise would be appreciated as I have never performed a head gasket job myself. What brand gaskets do you guys recommend? Are the ones sold on this sight good? Thanks!!
 
Drained the coolant down so I could shine a light down radiator. The core does look somewhat plugged. Took a thin wire an was able to push the crud out fairly easy. It is not corrosion, but more of a rust mush! Can this be easily cleaned with water and hose? Nearest radiator shop is 100 miles away and we have a plow bee next Sunday and would like o use the tractor.
 
Take the bottom hose off and make an adapter to give it a blast of air. Fill with water and give it a air blast to help remove the crud. Have to use caution as to how much air to blast. Or like I did on a Dodge Cummins pickup... Drained coolant down and put in a couple of gallons of vinegar and ran it a 100 miles and flushed and filled with antifreeze. Heating problem gone.
 
Lyle: Installing heads is no small feat. Both the head surface & block deck must be thoroughly clean. A professional shop will check sleeves for cracks as well as the heads, and also sleeve protrusion. The heads and attaching parts must be re-installed in a particular sequence, as well as the head bolts tightened in sequence, then re-torqued as the CASE service manual outlines. You should be shopping for a Head Gasket Set, aka "Valve Grind Set", that contains all the gaskets necessary for re-in stalling the heads.
If your radiator is partially plugged, remove it, turn upside down and flush and flush and flush.
