Yup just had a few engines done. recently fired up one engine in a 67 bird and is running and driving now. 1977 400 with 6x -8 heads Have another engine to assemble, a 1967 400 with 670 heads done at the machine shop for one of my customers recently. Used brand new forged rods with good bolts and icon pistons with a dish to run on today's gasoline. In the cylinder heads we went with all new stainless valves, new valve springs and retainers......etc. bronze guides and a good quality multi angle valve job with a carbide cutter. Complete assembly ballanced. The engine block was also line honed and the decks were squared then the block was thoroughly cleaned with brushes through all oil galleys and finished off with new cam bearings and freeze plugs and the plug by the distributor has an oil hole to oil the distributor gear.
