Thanx for the replies.
I don't think I will complicate matters by screwing around with my timing just yet.
I am reasonably sure it is a recurring problem with my intake manifold not sealing on cyl 1 and 6. I have replaced the gasket twice from it being blown, each time thinking this time for sure. Literally 1/2" piece missing on cyl 6 last time. I think I will take it to a machine shop and have the surface checked for true and maybe milled this time.

I been meaning to stop by the shop, and intend to when time permits. You open on Sat.?
