Cylinder Head Freeze Plugs???
Having some trouble finding the freeze plugs that go on top of the cylinder head. There are 6 of them and they look to be about 5/8" and sit between the valve covers and injectors. Is this a cummins only item or can I just pick up a certain size from a parts store? Someone on here has to know I searched around but found nothing. Thanks

Probably an old number but should still cross reference:
Cummins part number 3902606; Plug, Expansion.
Rumor is that some have been replaced by tapping the hole with an NPT pipe tap and then replacing the soft plug with a pipe plug. Measure first before you attempt this.
