I would be intereted in the heads if you get it. I need them for my Chevelle.

i found 074 stamped on the front of the heads. i did not find any vin# near the oil filter housing. it appears that it has never been stamped there...the surface is still somewhat rough.
thanks

John, you are looking for a casting number on the heads. This is a RAISED number located under the valve covers. It is not stamped. You need to have the heads off the car to get the casting date as it is located on the underside of the runners. The casting number for the ZL-1 open chamber heads ends in "074" it is a 7 digit number.

John, was there a VIN on the block by the oil filter and what was the casting date?

[john ferguson]

could not find a vin # anywhere...where would the casting date be?

It is a raised number on the driver's side of the block near the front. The number is upside down.
