Volvo Penta 531 head 1000531 aq131 b230 aq151 cylinder head Marine "A" Cam

Up for sale is a good condition Volvo Penta 531 head 1000531 aq131 b230 aq151 Cylinder head this is the best flowing of all the Volvo Red Block 8 Valve heads , marine "A" cam  in excellent condition,  the head is flat and true guaranteed no cracks . The #4 exhaust ring has been installed , and while the exhaust still seals up properly , I would do some work on the 3 and 4 exhaust ports especially if you plan on using this with wet marine exhaust .  These heads have an issue with corrosion on the back cylinders . I would weld them and port them for longevity. With that said you may just decide to Bolt it on and get back on the water . !!!
