Anybody good at identifying SBC heads?

I've been digging and can't find this head marking anywhere. Can anyone assist?

I attached an image. I can attempt to get a better one but it's tough on the truck.

Re: Anybody good at identifying SBC heads?

As I remember thems are pretty good heads #xxx882, maybe #xxx624 , 1.97 intakes 76 cc chamber

Find out what the cast date is. There are heavy weight and the later light weight that were prone to crack. I think those are the earlier heavy weights

I have the 1970 #3932441 heads on my K20
