Yep, I forget to say how much PSI.   Youre right 100 will do fine.  Get down to 80 or below and it starts getting more difficult.

The hose trick works well.  It's a good tip.  I usually use a short piece of vacuum line.  Less support but more flexable and better feel than hose. Also a bit tricker until you do a few.  The hose is probably easier on cars with a straight shot, like our C3s.  Where the angles are worse the vacuum hose wins.  Both work very well.

Well I finished the seals and did the static adjust... question is... it is running smooth and no clatter... do you think I should do the engine running or leave well enough alone...?

Running smooth and no noise after static adjustment.  I would leave it alone.  It should be good.

If it's done correctly the static adjustment is very dependable.  I do it frequently.  I always do it with new lifters, then install the valve covers complete with sealer before I ever start the engine.  I know I'm not taking them off again.  Far less mess that way.  With lifters used over 50,000 miles I always do the running adjustment.

Well I guess I did get lucky with the valve adjustment, but no luck with the lottery. Actually I did like in the manual (#1 TDC and all associated intake/exhaust valves then one full turn to TDC again and those valves...

.. oh well I'm happy with that... I can't believe the difference with the oil use either... I never would have believed that much oil would burn thru the valve stems in  a couple hundred miles(couple seals were discentegrated and the rest cracked in half)... .. now not using any oil  ...and no smoke on start up ...she was also burning on idle but hard to see except when someone came behind me at night...

Did mine on Saturday...no more blue smoke when I start it... It's great.

 The little o-rings were either completely gone or so brittle than when I touched them they fell apart. I put umbrellas on.

 Thanks everyone for the advice !

I generally do both..  if you have a good static adjustment it is fine..  I feel that a dynamic adjustment can account for individual variations in lifters betters and therefore I do a static to get in the ballpark then a dynamic to get it perfect..
