GM experts needed

Hey all, I'm learning how to reference the casting numbers found on my engine to Mortec's website. As of right now I am only able to get the head casting #'s and the Engine code. According to Mortec's site this is what I have for heads........33417369...90-up...350..........Gen.I Goodwrench crate motor,"Hecho en Mexico", 76cc

I have yet to pull the motor out of my truck so I have no block casting numbers. I do however have the engine code found on the passenger side front of the block on a pad as follows, 2m0102 7vp.

This motor was bought as a crate motor and I have done nothing to it. By the info provided can anyone tell me what I may have, ie. JUNK, MEDIOCRE, or a nice foundation for a mild or wild build. I'm just curious.

Thanks,
Eric
