Default Assistance needed: Info on the use of Honda Replica cylinder heads

Long story short purchased a head for a rebuild project that I plan on working on in the future. Question for you experienced folks, any issues you guys have with using bare heads that aren't stamped PR/P? Looking for suggestions from experiences in the past. I've attached some pictures of the head I purchased for my build but looks like there are not any stamps and wondering if I should be concerned. Visual inspection is it looks like pretty decent shape so just looking for if I am missing anything or if I should have it checked out. Worried about potential warping or fractures that the visual eye otherwise wouldn't pick up. Trying to prevent building this thing just to have leaks down the road. Person I purchased it from has pretty solid reviews. Appreciate your input.

Quick update the seller informed me that its a replica head. Sort of having second thoughts and most likely will return any thoughts on that from folks who have dealt with replica heads?

Spray bars are missing. Casting looks pretty rough.

So I went ahead and shipped it back to the seller just didn't get comfortable on building the head out using it. After looking around I think my best shot is to simple buy a longblock from a reputable place and go from there.

Definitely not OEM-casting (no id-markings, darker cast finish). There is (or was) some aftermarket-head on market but have no idea what their real quality is.

Quite interesting, combustion chambers are smaller P72 type but intake ports and coolant outlet positions are from PR3.

Yeah noticed that too thought it was a p72 head then noticed the square port for the intake manifold, the guy said he’s sold many of them with no issues but I went ahead and sent it back
