I need to purchase a new head for my 22re that sits in my 94 truck.
I would like some recommendations for a reputable seller that you had purchased a head from and had good luck with the head.
My recommendation would be to get a bare head and transfer your oem camshaft, valves, etc
Lapping your valves to the head doesn't take much time, and all your used oem parts will be of vastly better quality than anything on a new loaded head.
I bought an Enginetech complete cylinder head from RockAuto 5.5 years ago for my 92 pickup with 22RE. It's still working just fine. The head was made in Taiwan. It was a complete head with cam, springs, valves, and etc. ready to bolt on. I did buy a set of Enginetech head bolts, and then used a Toyota head gasket.
Just looked at RockAuto, and the complete cylinder head from Enginetech is not available for your 94. ITM Engine Components complete cylinder head is in stock for $337.79. An Enginetech bare cylinder head is in stock for $185.79.

When someone installs an aftermarket 22R# loaded head AND has problems, the odds on favorite for issues is the camshaft. Most notably the lobes just getting ground down to nothing(rockers aren't terribly happy at this point, either) and sending debris all through the engine.
Now, I've read many theories, and some sound reasonable.
1) The cam material is inferior(soft). Good possibility. I think the rather involved break-in instructions that are recommended with these cheap aftermarket cams reflect this.
2) The springs are stiff. I compared used oem to new aftermarket and the aftermarket springs seemed much stiffer. but I had no accurate way of measuring just how much stiffer.
3) the valve lip on the aftermarket is thicker, along with the washer plater and retainer, making the spring even stiffer. in my case, those individual components were noticeably thicker. I didn't bother to measure by how much. The theory was the thicker pieces decreased the area where the spring goes, increasing the spring tension and increasing the resistance on the rocker. Sounds plausible.
Maybe if you follow the break-in instructions to the letter it tempers the cam.
i dunno. After dealing with one camshaft that got worn to hell in a few hundred miles, sending aluminum and steel debris all through my engine, I opted for installing used oem valves, hardware, and cam.
But, as mentioned, others have installed loaded heads with no issues. Jut be attentive.

That is exactly what happened to my sons camshaft..got ground right down at rear of camshaft. He thought maybe not heat treated. Forget who the seller was. I would have head done by local shop or reputable seller..cheap parts are for poor folks,,and ya know the saying "poor man pay twice"
