Flat cam is caused directly by antifreeze or water in oil . Know all about that . Wipes lobes and lifters . Cam was ok , probably , before leak. .in one case cracked head ( almost never on a hemi unless frozen) other time blown head gasket .
Maybe water is making it from one side to other via exhaust passage under carb , or across intake if that much water in cylinder .
Most likely blown head gasket ... .or possibly some kind of water leak into intake or valley at head port surface , particularly if work done involved resurfacing head . Can screwup fit / sealing of intake .
Before disassembly check timing setting may have gotten advanced too far somehow , hurt both sides?
Dry out , by cranking , compression test 8 cylinders if heads on . Clue to if one side or other is truly hurt , even with hurt cam , might be meaningful . If 8 good/ same look carefully at fit of manifold .
Do you have metal shim gaskets ? They rust out typically from cylinder bore to a water hole near cylinder , then go between two adjacent cylinders , probably because water in one generates high pressure blows into neighbor . Get best gaskets they have , see hot heads. Latest stuff on that .
Blown on both sides kind of says not torqued right or metal gaskets rust ? Or excessive timing . Hemi hates more than 30 degrees , lose power too ( advance all in) . Check timing damper marks ?
Might try cranking the motor with head bolts in place — but loose ? May pop it . Breaker bar handle in port once manifold off ? Crude but ought to do it , wrap end in a rag ? Remember dowel pins ...
Once antifreeze in oil , might have gotten bearings too . Careful check , at least .
Sorry you have to deal with this , been there long ago in a Boston January snowstorm in driveway no garage . 20 degrees out Pinched frozen fingers so bad still remember it . My problem that day was those damn exhaust manifold studs . . Head came free but held by frozen exhaust bolts. Ready to holla!!
Hope it helps , hard to say from afar ...
