The only ID #'s on my 93 are on the deck up front, no optional vin stamped on the side and non at the rear.

 

source/built in flint michigan.

 

Oooo! Yes! And my heads are serial numbered #19531 and #19531A. Any identification in the head numbers? They were also labeled 16 and 18 on the inside with marker.

 

that's not the casting number on your head...should be a longer number ending in 643, 561, or 374. i'm guessing your's are the 374's

 

the good casting # for the lt1 is 10207040 and its under the valve covers. do u see any other markings? if not that number is probly a manufacturing number. lloyd leaves a sig and level of work marking on his heads and i assume any reputalble machinist that ports heads has one. mine have a date and le2 on the end with my name also ingraved by lloyd there.
