He means , I think , that motor home heads have special water jets, and head gaskets, possibly block holes etc around exhaust valves to locally cool that area better . Got too hot locally on long pull up a hill in a truck or motorhome= detonation. . Of course --all v8 are water cooled heads! But as pointed out , this would not have high performance heads or pistons anyway ; low RPM, low compression . Truck stuff. So ?? would use older 300 heads 10;1 pistons etc. but using this block, I would check old head gasket on block face be sure water holes are there or put them there for old head gasket water patterns. Compare the two block tops. And to be sure head fits it ok. There is info on this , out there, I do not know all the details. Industrial blocks probably the same cooling.
Might put Edelbrock heads on it. Depends on goals.
