I'm looking for any tips on the next steps of my 383 refresh from you guys with experience. I just received my 440Source heads and they are about to go off to the machine shop for a good once over and a milling. My short block is 40 over with KB162 pistons that are .027 below deck. Block was checked, crank was polished and rotating assembly balanced..etc by a machine shop. My cam is a hydraulic flat tappet comp xe274h, Duration 274/286, Lift .488/.491. A different machine shop will be going over the heads for me as I wasn't quite happy with the shop that did my short block. I have fel-pro 1009 head gaskets with a compressed thickness of .039. I still need a rocker arm set and pushrods. Im leaning towards just the stamped rockers (its not a race car). I have a push rod length tool though. Can I just tell the machine shop that I want these heads to be at 75cc combustion chamber? Should I do any piston to valve clearance checking before I request that volume? Can i go more? I need to get as much as i can milled from the heads due to the pistons not being at zero deck. The KB162's have a decent valve notch. Any advice would be greatly appreciated!
