Also, what power valve setting should I get. I'm thinking like a 6.5" or less right? last time I did a vacuum check I had about 10".
TAKE THE CARB OFF. It's only 4 bolts, 2 fuel fittings, and your linkage. It shouldn't take you more than 5 minutes to take it off and do the job properly. This way you can clean everything out properly, and set your butterflies. You CAN'T check or set the butterflies with the carb bolted down. To pick a PV you really need to know how much vacuum the engine is producing at idle. With everything you've got going on right now you really won't know, start out with a 6.5. Yes clean out all the passages main body, baseplate, and metering blocks.
