When initially setting valve clearance upon re-assembly put #1 cylinder at TDC and adjust both vaves for #1, and also the exhaust valve on #3 cylinder, and the intake valve for #4 cylinder.
Rotate engine now so that #2 cylinder is on TDC, adjust both those valves as well as the intake valve on #3 and the exhaust valve on #4.
Keep in mind that with hydraulic lifters there is a 15-minute bleed-down requirement that is done by having each valve positioned wide open and let the pressure of the valve spring take out the pressure in the lifter by the 15-minute wait under pressure. The zero-point is then determined by opening the adjuster screw until the valve closes and pressure is no longer present on the screw. Then, I think 1 and 1 half turns will set it. Not sure exactly about this but initial adjustment is with each valve seated and the lifter fully collapsed by the 15-minute bleed-down first. Check the FSM for your engine, it is outlined better there as a two sequence procedure with each step outlined more thoroughly.

i'd like to see a compression test as well.

The EA81 has a two-step initial valve adjusting procedure which shouldn't really vary from the EA82 much, at least as far as Hydrailic lifters are concerned.
There is no adjustment for the valvetrain of the EA82. You either have good HLAs and Rockers or it's bad. I'd try getting some new HLAs, rockers and a new cam. If it was run with a lifter cockeyed then it surely mared the cam lobe.

The cheapest I've seen is $544.00 for the head and cam.

It's actually the rythmic clicking of the rocker arm knocking against the cam housing. The belts and tensioners are all in good working order.
Hitting the Cam housing? That isn't right. The rocker shoudn't copme anywhere close to the housing.
At anyrate, I think youd be fine to just replace the Cam and rockers. You're head is probably fine.
If you need a set of Cams and rockers I have some. You have to be careful cause the Carbed cams are different than the SPFI and later years. PM me if you are interested. You're car is an 85, and you didn't mention a turbo, so I'm assuming Carbed. Is this correct?
