really high idle

i bought new vac hose yesterday im going to replace it in a little bit, wont get a chance to test the trouble shooting tips til wednesday when im off again. i have to fix my leak out of the bolt holes on the front cover today and let the sealant dry before starting it up again. also realign my radiator, i think its too low, so its not cooling/flowing properly.

the carb is a holley 600cfm 80457 or 80783s electric choke rebuild by an ebay seller that had really good reputation.
