Your thinking is similar to mine Ricey. It would be to your advantage to assemble a HRC jet / carb kit if you can. If you ever run open carbs or want to go to SS/SP settings, you'll need them. If you don't, you should be able to sell them on without losing money. Yahoo Auctions is worth keeping an eye on.
