Good plan. As long as you write down your base line, you can always go back to it. I'm pretty sure those blocks come with .031 emulsion. That's quite a bit if you have 3 holes open. More emulsion usually means you need a bigger jet.
The latest issue of Car Craft has an interesting article on carb tuning when you are trying to correct getting on the booster to soon and some other things. They still didn't have the power valve timed correctly. SMMFH. But there is some good stuff in the article. Which is going to affect my tune up. Im going back to 1:1 throttle linkage and power valves in both ends.
