You want to make cylinder-heads? I admire you for this, but I wouldn't know too well. If you had the tooling you could machine them. Otherwise you'd need to cast / injection mould and then machine them. Have you got the tools, and out of interest where did you get the rest of the engine? L
To make your own, you are going to have to work from billet aluminium and mill/ turn them ! If you have to ask the question, it seems you don't have the machine shop experience to do it. A shop that can do it will charge a small fortune for one-offs. Keep trawling Ebay for the bits ! What's the bike ? Steve
You probably wanted to comment on the question / answer, but the author hasn't replied yet - maybe won't. L
Yes, sorry about that. Steve
It's interesting, but I'm not holding out much hope for an answer. L
