I have a complete 1850 cylinder head that I was given because I have a Stag. As you guys will know this will not fit on a Stag and I need to have a clear out. It has the cam and tappets etc installed and looks pretty good in there. The head face looks flat but there are a couple of small areas of corrosion about 0.5mm deep which perhaps caused a water leak and caused it to be replaced. Also some porosity as seen in one of the photos but I doubt would cause a leak. Sorry but the photo quality is poor as uploaded here- happy to email them separately if you get in touch.
Would accept scrap value- say £30. Will be happy to hand it over at the Stoneleigh show this February to avoid postage costs.
