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.
