Thanks Jerry. Truck was running 7 years ago with no issues. I replaced the valve covers before firing it up with the sniper, there were no "vortec worms" found. The cam is an Isky 270 mega cam. 0.465 int/ex lif so not a real high lift. Have used this cam before with no issues.
Cutting the seals at the top would not work as there is a small wrap around spring at the top of the seals.
Buddy and I think that from sitting the seals might have dried out and stuck to the valve stem.
Used a part from a leak down test. Put each cylinder at tdc, screwed in fitting from leak down apparatus into the spark plug hole. Used a ratchet strap from frame to dampner to keep engine from rotation. Used 35 psi to each cylinder. Used a spring compressor, pulled the keepers, spring and retainer washer. Removed buggered seal. Seal kit comes with a short straw, use it, protects the seals from damage from the spring retainer detent on the valve stem. Apply oil to new seal, slide on, set seal in place with a 1/2 in deep well socket and small hammer.
There's a blurb on valve seals replacement without pulling heads. Tedious project.
