<VV> Further Problems - was Oil Issues

[shortle]

Wasn't this a "rebuilt" engine? One of the first things I will do on an engine before assembly is verify EVERY bolt hole is clean and has good threads including spark plug holes. I guess you know this now. If this is not a rebuilt engine I might find a good used (number matching) head and install.If engine has been recently rebuilt I would remove this head and get it to a competent (Corvair) machine shop for help. Indeed you are right. This is not for the "faint of heart".
