What's the casting # on the heads?

Looks like #6 cylinder lost a pushrod and the cup caught the aluminum rocler.
Head casting numbers are:
253184-D
X
08058
AAWJ 340

Also looks like one on the left side of the engine lost a push rod also.
#6 is also the one with the exhaust valve mark in the piston.
