Back to the basics, I usually set my valves(hyd lifters) old school:
 Tighten the rocker nuts till there is tension on the pushrods but you can still turn them barely.
 Then put those rocker armclips on(to prevent getting oil in my eyeballs   :laugh )
 Fire the engine and do the tighten down thing on the rocker nuts till the clatter goes away and go 1/4 to a 1/2 turn more and call it done.
 
Well I also have seen the top dead center, set the lash to 0(I think) on certain cylinders then turn it 90*, set 2 more, Turn it 90*, set 2 more, repeat till they are all at 0 lash.

Now the question, if you do the top dead center turn method is that a done deal? And you shouldn't have to run them again after you fire the engine.
Or no matter which way ya do it ya still have to make a mess(setting them while ya run the engine)

Wow, didn't think anybody did valves that way anymore, that sucks! :eek There is only way to adjust valves accurately. E/O, I/C!. To do the intake, rotate the engine and watch the exhaust, when it just starts to open, you set the intake. To do the exhaust, rotate the engine until the intake is almost closed, set the exhaust!. That goes for any type cam, no need to run the motor!. :)

I do that on solids, but I thought hyd lifters needed the oil pressure to be set tight. Is there a measurement with no oil psi for hyd lifters?   :confused No biggie just  :rolleys wondering....

You do it the same way, just tighten the nut down until there's no freeplay on the pushrod(zero lash), then add your preload, done deal no mess!.. :)

OK, this won't help KC out, but a humerous story about adjusting valves:

The first time I tried to adjust the valves on my 396 I used the method of TDC (intake), adjust half the lifters, TDC (exhaust) do the other half.  By the time I was done I had it so screwed up that the poor thing wouldn't run (I had collapsed the hydraulic lifters).  Finally I backed all the adjustment nuts off completely and left the motor overnight.  Next morning I tightened all the rocker arms down till they were snug and started the motor and adjusted them with the motor running.

Now however, I do it like GoFast said.  It is definetly cleaner.  :D

Yup, blows me away what he is getting out of those pontiacs, makes me think of getting a boat set up for and olds and sticking a pontiac in it.
