Replacing cylinderhead

[Ian Williams]

Thank you guys for your input, I have experimented with various products, Hylomar spray being one already mentioned, however I have not been entirely confident of the sutability in anything for all applications thus far. I have however not tried 5920/5990 so based on your comments that will be my next avenue, I would also like to clarify for anyone reading that I am discussing higher than normal compression ratios when stating I am not satisfied with some products, and on an LC head with GOOD faces and water passages a smear of grease seems reasonably satisfactory. There is though, no matter what anyone else says, more of an issue sealing modern gaskets than there used to be with traditional copper asbestos gaskets. I don't wish to scare monger but simply warn owners to beware, I have lost count of the number of engines which have been brought to me for work and once the head has been removed there is evidence of water damage to the bores and valves and seats.
