I've managed to round off an Alun key bolt and can't get it undone.. Before I attach the Alun key to it with metal epoxy, has anyone got any useful tips to unscrew it easily?

Weld to it metal epoxy won't hold

From experience, with 70's jap bikes, drill, eezi out, replace with stainless. simples.

can I sell my tat now?

Yes, those soft cheese allens, set down a well in the shiny alloy casings Fond memories!

OP, if the head is sticking up proud, you might be able to lock a molegrip onto the head and wind it out carefully.
If not, drill and easy out should work!

A plus would be use a drift and hammer to see if you can shock it. And if possible use a good amount of heat, then let cool

they let me slide plus I only have a set of ported heads from the chevy left now

Gonna clean them up fully, paint them with lacquer and sell I think

If it's one of those with the head proud of the surface try filing two flats on opposite sides and use a spanner.

I don't have any tat to sell yet.

Irwin extractors work on allen bolts if you have sufficient access.

i don't think metal epoxy will work on capheads.

you could try welding a nut on or filing two sides flat so you can stick a spanner on it.

depending where it is, replace with 12.9 caps if you want to replace with caps that is.

There's a manoeuvre I call the 'reverse James Martin' where you hammer in a slightly larger hex. It might need a little but of a taper ground on it to get it started, but they go in eventually. Imperial sizes can give you some useful intermediate steps in between the millimetre sizes. That, plus the vibration of hammering, can shift the bolt. And give it a good soak in WD40 or similar overnight.
