Re: casting numbers on c5s

the heads have a casting # on the outside either lower left or lower right corner of the head BUT there are only the last 3 numbers of the part #. 243 would be the number of the LS-6 head. the LS-6 blocks have a recessed machined surface where the stamp pad is on the old SBC where the std engine is "as cast"

There are two different casting #'s on the rear drivers side of the block, to differentiate those used for LS6 and LS1.

I don't know about head casting #'s.
