3904390 GM 396ci Closed Chamber Cylinder Head Chevy BBC 396 Corvette Chevelle. Pair of cylinder heads. Both were cleaned and checked for cracks and had new exhaust seats put in before customer bailed. One had some damage on deck but it looks like it can be resurfaced and cleaned up without a problem. I have more pics if wanted. Date matched pair. Some spare valves and springs come with heads. Sold as is.
