OK, I did the rope trick and made a home made valve spring compressor to take the valve springs and valve seals out without removing the head. Surprisingly this was easy to do. it was easier than taking the intake manifold off even. I cut a window in a section of 1" steal tubing to access the collets I made it a little over a foot long and welded on a tee handle. it was very easy to hold the spring compressed using my chest pushing the T-handle and have both hands free to get to the collets. Rope put down through the spark plug hole filled up the combustion chamber and held the valves up great.
I saw no glaring issus with either the guides or the seals. The second intake guide might have the most clearance but I don't see how the valve could be rocking enough in the guide to make the seal not work. I replaced the seals and put it back together. Very little differance was made. I can drive it around in vacume and boost up to 5 maybe 10 psi and not see smoke. Full throttle 15psi and she smokes some.

A number of people have reported that non-OEM valve seals have had very early catastrophic failure. If it's only a couple of weeks ago I would cut a deal with the shop - you provide them with a complete set of OEM valve seals and they do all of the labor for free (including R&R the head). If you have to R&R the head yourself then they can pay for the seals as well. I presume they have *some* sort of a warranty - especially a borked seal in less than 30 days.

The other cylinders are bone dry. all valves were taken out checked and new Viton seals were installed a couple of weeks ago. Me thinks the machine shop that did the work messed up or missed something. Bob
