SBC head decoding?
Years ago I bought an assorted lot of disassembled small block chevy's. In the lot there was a 283, 327 and 350 4 bolt block, cranks and cams for each, and two sets of cylinder heads. One set of heads had casting #3814480, which is a 283/327 from 60-67 1.72 intake 1.5 exhaust 70cc, so not an amazing or rare head, just an old regular from the looks of it.
The other pair has me stumped. It has an irregular casting number, 8786886 It has a weird triangle of letters A D N CANADA GM2 on one head, CANADA GM1 on the other. Any idea what the heck these are? Thanks!

might try www.mortec.com they have a list of head codes on their website for identification use.
