Quad carb setup information help

Rat Bastid, I've gotta get some additional information such as verify my timing and my vacuum at idle which I hope to do tomorrow. But reading your post about idle air bleed I wanna make sure I but the correct parts. Here's an address to some on eBay I can purchase if there correct. ( (10 Pk) Blank Drill To Size Holley Carburetor 10-32 UNF Air Bleed Screw In Style | eBay )
Also what drill bits will I need and should I look into a pin kit to be able to check sizing.
Thanks for your help as this will be all new to me and I'm sure ill have a ton more Questions.
