Thanks Dave, Al and Ron!
Excited to do this. The ratio of engine work to research and discussion is currently about 1 hour engine work to 4 hours of research and discussion!
All good points - planning to pull the manifold and valve spring gallery plate next as it is fairly obvious that I am pulling all the valves this weekend and measuring them for wear and eccentricity and run out.
Any one know of a good machine shop for valve and head work in Eastern Massachusetts?
