head rebuild
I rebuilt the heads on my 84 351w. I have a picture of them complete, but basically it goes like this.
1. insert valve through head.
2. put on valve stem seal, spring, retainer, then collets. You'll need to compress the spring here.
3. Next, at least on mine was the order of the rocker and assorted parts. it goes (I don't know all the correct names, but rail, then rocker, then the rocker pivots? ( I don't know if that is what they are called, but it is what the rocker is pressed against and pivots on.) then they bolt on.
Thats the best I can remember.

I have several questions: First, why didn't the machine shop reassemble the heads? Next, were the valve seats and valves reconditioned? Were the springs checked? Are you putting new valves and/or springs in?
I found using a deep socket the new oil seals go on very nicely. You probably will not have a sleeve in the retainer

You have both rotators and retainers. The ones that rotate are called rotators and the ones that don't are called retainers. The spring used with a retainer is going to be longer than those used with a rotator. I assume either all the exhaust or intake valves had the rotators and the other had the retainers. That is how it was on my heads, but I just replaced the rotators with retainers so I could use the same length spring on all 16 valves.
Another thing is that if they ground the seats at all you might need different length valves.
