Jim, Is the date code for the heads or the block. I assumed for the block but then I reread your post and I think you meant the date code was for the heads.
I looked up the head casting number 3814480 and it shows use from 1960 to 1967 on 283ci or 327ci motors. The Heads have 70cc chambers, 1.72/1.5 valves.
Your YH application code was used in 1966, 67 and 68. All Truck motors, all 327's.
The 1967 350 Camaro motor used application codes MJ, MV, MS, and MT.
3892657 Block casting number is for 1967 302ci, 327ci or 350ci.
