1989 Iroc Head Casting Numbers

Just bought an engine from a guy who said it came from a 1989 Iroc. It's a complete 5.7 tpi engine that runs. I checked the rear of the block which says 5.7L and the casting number inside the driver side head valve cover is #14101083, G037. I looked at Mortecs casting number list but I don't see this number. Can anyone tell me about this number? Thanks
