I got it, 30#torque I had to change valve seals without removing the heads. Foundthis site and modeled a tool after it. No action pics but it worked great. Built a adapter out of a spark plug and a piece of hex stock. Used air pressure to hold the valves in place when I changed the seals. I only dropped one keeper and I thought it hit the floor but 15 minutes later I found in sitting on the A frame
Next time I am going to buy a few extra keepers. The hardest part was getting the right angle on the stud.
