Help identifying pistons and cylinder heads

Thank you for the info! Maybe if I go for these ones, instead of the hydraulic flat tappet ones, I can run a solid flat tappet instead...but then I will have to spring for some adjustable rockers, as I don't think the factory stamped obviously can be used....Im just watching the budget fly out the window as I think right now! lol

They are a damn good deal on Black Friday though for sure. Would you be confident running these heads out of the box John?

The guides are looser than Edelbrock guides which I prefer. I found one very loose guide (.003 over) and the chambers weren’t finished on the same set. These were bare heads and probably would have hopefully been caught if they were assembled. This was out of about 15 sets. I don’t recommend running even the best heads out of the box as they should be taken apart, inspected, and cleaned. They have a very nice looking set of upgraded 1.5 rockers that I had in my cart several times.
