Ken, apparently my motor had been rebuilt by the PO, unfortunately I do not have any documentation to support this. I was told by the fellow assisting me with this issue that the engine as far as he could tell looks like it had undergone some level of rebuild not that long ago due to the condition and cleanliness of the heads and intake once they were removed.

We also found the exhaust block-off plates on the intake manifold tray. I never experienced vapor lock issues although I never really put that many miles on the coach this summer.

I will discuss with Dick Paterson the carb rebuild and distributor service before making a final call on the EFI decision.

Also noted on the spark plug gap, I did a bit of research on this and the suggestions varied from 40 to 80, I'll know better next time, I plan on a fresh set of plugs before final start-up.

Thanks again,
Mike
