Edelbrock sells a tune-up kit with different metering rods and springs. The kit is a little pricey for what you get, but it's helpful. It's best for tuning at the drag strip to get your full-throttle settings dialed in. The Edelbrock manual is very good- I follow mine like a Bible. If nothing else, you can pull the rods and springs out of the carb, and if the paint is still on the springs, and the numbers are still readable on the rods, you can compare it to the manual shows as being stock for the carb. You only need a 1/4" drive ratchet and a rag to throw over the mouth of carb- it's super easy on these. I run an RV-type cam in a mild 318, and the stock 1406 set-up was great for me- that RV cam shouldn't be causing you any vacuum problems.
To check final mechanical advance, you disconnect the vacuum line from the distributor, plug it or clamp it off with visegrips, and then rev the engine up slowly until the timing mark stops moving. I like using a dialback timing light for this, but use what you have. It helps to have an extra set of hands for this- one guy on the light, one guy on the throttle.
As for the PCV, check where the valve is installed- if it's a homemade installation, make sure there's a baffle behind it to block flying oil from getting sucked up.
