Hi,

Believe a 1974. The numbers on the heads and cams should state their application. Hope this helps.

Joe R.

The cylinder head number as stated above is a casting # for a right side head. The left side head will have a different number.
Similarly, the cam number is a core casting # for the left side. The cam code numbers are the important ones.
The numbers supplied by the OP are not part numbers.

the cam code numbers Frank is referring to are stamped on the back surface of the cam.
