Knowledge bomb needed for 71' chevelle

[71goFASTER]

After a couple months of patiently waiting and putting this aside I hope to have my car back from the shop. Front and rear springs replaced with Hotchkis, headers from Hooker, new cam, resurfaced heads and springs. Custom x pipe and exhaust work. Planning on the stage 2 sc&c upper A arm and of course Kore3's c6 brake kit before mocking up for wheels and tires. The excitement is at a 10 to say the least! Any other suggestions from yall would be great!
