I think they are 5.5" inches long SS. STOCK GM valves.

After 6 hours of measuring shims for rockers and grinding the heads and taping up the block I managed to get 1 side of the rocker together......... Did a quick leakdown test numbers are coming in 12-14% so that means the head gaskets are sealing at least! I highly suggest you buy this leakdown tester I love it.How about some pictures.
What caused you to have issues with the rocker assembly geometry? The leakdown test doesn't lie does it? I bought one several years ago.
