Con: Thanks. bought the car about a month ago. It's an old build from the paperwork I have on the car. Probably been in the car for at least 20 years maybe even more. Not a lot of miles on it since it was built from what I can tell. Going to pull the valve covers and adjust the valves and see if that helps on no 1 cylinder specifically. Have no idea when the last valve adjustment was. Though there is no real valve train noise. So we will see.

Bigchief: Looking to get it through the summer and plan will be to pull the heads this winter. Get a good look inside. Heads will be changed out regardless and new ones installs. Combustion chamber size of heads will be set by how low the pistons sit in the bore for a total volume that will let me run Premium (91 Octane) all day long. Would like to do full engine rebuild but too many other projects and money commitments to go that route. With 180 PSI across the board less no1 cylinder at the moment I'm comfortable as well going a while longer before having to pull the motor and freshen the bores and rings.
