Purchased a valve head assembly a few days ago from AutoZone, followed all pre installation steps required for the new head, found sealant missing in critical areas, gally plugs were only finger tight, which gushed oil after install and start up. Lifters sounded as if they were already bad.Returned head a couple days after purchase to AutoZone under warranty and got a replacement.Decided to tear down the entire assembly to make absolutely sure nothing was missing and everything was sealed as it's supposed to be. After spending all day cleaning and reassembling the valve head, priming the hydraulic lifters which were completely dry and seized in their holes with rust, and cleaning up said rust and small scoring marks in several spots, and cleaning off carbon build up on several valve stems, I discovered that the intake cam had been broken on the timing gear end.I'm now waiting on my THIRD head assembly because this company has absolutely ZERO quality control for critical components and parts they sell.The car I'm working on was supposed to have been finished a week ago, now I have to wait another week to get the THIRD head in for warranty replacement, tear that one down to make sure that one isn't all f***ed up, clean, lube, and assemble said head, then install it into the vehicle.I'm lucky I'm doing this at home and not at work, or I would be losing money having this car just sitting in my bay, waiting for parts that should be as simple as lube everything up, transfer the other parts onto the new head with new seals and gaskets, and it's ready to go.This is absolutely ridiculous that I have to tear down the "remanufactured" head and do the job which this company is supposed to be doing themselves in the first place. It literally looks like they just resurface the top and bottom surfaces, replace the valve seals, coat the outer surface in rust resistant paint, bag it, toss it in a plastic crate, with nothing more than zip ties to keep it from banging around.
