I run 24 degrees total advance,no vacuum,about 16 at idle,all in by 2800 rpm,,,I use a holley 950 and vic jr intake and big headers.

also of note, your valve springs may have gone soft from sitting long periods of time with out running,,,think about when you park the car at least 1 valve is wide open and how long you left it like that???
Those are all good points Vinnie and I appreciate them. I'm going to re-check valve settings and check to make sure the the right springs stop bushing are installed and not contributing to excessive timing advance. Try a set of new plugs as well and see where I am.
