Can you fix a cylinder head with JB weld?
And which JB weld to use? How high will the peak pressure be during combustion of a small motorcycle engine? Better to just spot weld the holes in the head?

JB Weld will never fix a damaged cylinder head. Take it to a machine shop to be welded and resurfaced, if it's a two-stroke engine. If four stroke, it will need a bit more attention to the valves.

No. JB Weld works great for small repairs, but it's not sufficient for even a small motorcycle engine. Spot welding *might* fix it, but it depends on what exactly happened.

You're a goof.. JB Weld won't fix a cylinder head. If it's an antique there's a possibility it can be specially welded and re-machined.
If it's a cheap POS put new motor in it or find a used head.

there's a couple videos on youtube of people who've repaired engine blocks and cylinder heads with that stuff, so possibly yes you can
no way is that the recommended way to repair of course
