Thanks for the replies.
Pretty sure the recent head work did include umbrella seals. the fluid in the intake was thick like oil. long idling before the head work produced a white cloud on rev. but this has stopped happening after the head work. even with the "oil" in the intake it does not smoke. I'll keep an eye on it. I found no oil in the PCV hose. I should've Q tipped it but it looked dry.
Also dealing with BV fuel leaks. seems like I'm using a lot of force on the inverted flare at the carb connection. the two halves look fine under a magnifying glass. Maybe I've forgotten how much force a flare connection requires. The line is reasonably square in the fitting.
