Current Chinese EQ Heads. Ports or mounting holes in wrong location? Pics here.

I purchased these heads in early 2022. The attraction is its a Magnum style head but drilled for LA intake manifolds. I immediately took them to my machine shop for a tear down and inspection. The results? Valve guides were spot on. Valve seats spot on. Quality of valves and hardware very good. I had the shop then cut the guides down for a cam up to .550" lift. I paid the shop all the while patting myself on the back that due diligence had been done. I began common sense porting and polishing these heads. Got one nearly done working on them occasionally. Then I read the post here about mismatched mount holes or ports - or both. I learned my heads were defective just like the the members heads who started the post. But the original posted caught it IMMEDIATELY and got a full refund. I had possession of my heads for over 18 months before I learned, and the business I purchased them from replied to my email with...no reply.
