Chevrolet 14014416 Cylinder Heads

Left and right Chevrolet cylinder heads 14014416 Purchased these from a 3 rd party who had them rebuilt. I never completed the project I intended to use them for. The seller provided the following information: While his info appears to be accurate; I have not verified. They were completely rebuilt/machined and not ever installed on a motor. They have Z-28 valve springs installed. They have screw-in rocker arm studs. They are only finger tight right now in case you want to add pushrod guide plates. The valves appear to be stock sized. They are a High Output design 5.0 L 305 cubic inchV 8 engines from approximately 1979 to 1986 They will fit a number of different GM motors. 1 exhaust port thread has been repairedHelicoil $600.00 firm CASH ONLY. Im selling them for less than what I paid. Please verify fit. While they appear to be a really nice set of heads with all of the expensive machine work being d 1 already, I encourage you to come and inspect them for yourself to ensure/verify the specifications and that they meet your expectations before purchasing them. That being said; returns will not be accepted. Straight forward transaction. No professional sales assistance needed. Local pick-up only. These are far too heavy to ship at any reasonable rate. Thank you for looking. E-mail or telephone onlyno texts. Alexander - 909-394-0773
