John I Posted August 15, 2020 Share Posted August 15, 2020 Hello font of knowledge, Having read of the challenges some have had with replacement head gaskets is there benefit of going to solid copper for a good road engine. If so what thickness is prescribed. Came across a firm who makes them called "Cometic" price about £77 delivered, anybody had experience of said firm? Any good sources of reliable head gaskets if not going to copper? Info greatly received. Cheers John Link to comment Share on other sites More sharing options...

Hi John Have read recently that folks have had problems with them failing. If NOS no problem but haven't they moved production to the Far East and I understood that was where things weren't so reliable. Have i misunderstood?

Nick Jones Posted August 15, 2020 Share Posted August 15, 2020 Flat block or recessed block? Flat you could use copper (and I think they do exist as Alan used to use them). Recessed block and you are stuck with composite. I understand (from Chris Witor) there is a problem with recent production Payen for recessed block.

So a normal Payen should be good to go, great that will be a few drinking tokens saved over the cost of a copper one. Just got to find a good source.
