The cam bearings should be pulled out so the oil galleries can be totally cleaned out...same goes for the gallery plugs etc.
Depending on whether the rod pins are pressed or free floating, these should be totally pulled down and measured.
Oil filter mount boss clean out, oil pump will be junk, check distributor drive gear, roller rockers is fitted may be ok but will need to be pulled down....
Oil cooler system if fitted will need total flush out.
Finally, debur the liter gallery drain slots of all those tiny pieces of shrapnel and left over factory cast metal....add some epoxied in screens in each of the drain slots and then paint the entire lifter gallery with Glyptol....heat lamp dry it for 12 hours...and no, it doesnt flake off and clog oil pumps....
Note...if the glyptol doesnt stick, the engine block isnt clean enough!
Bad luck there young man...
