Machine some alloy plugs that fit snugly into the injector bosses, have someone TIG weld them in place.

Probably best to make it so as it can be TIG'ed from both sides, so as deep as reqd to reach through.

I'd be more worried about the chav's nicking your injector blockers to spend on white lightning!

When I did this for my bike bodies I just drilled and tapped the injector holes, then used some screw in brass blanking plugs and some PTFE tape to ensure a seal - has worked fine since.

Welding them in is a bit extreme, the heat can cause problems. Epoxy glue is as effective if it's clean and It's not mega difficult to knock them back out if you need to later. Likewise, threading it rules out using injectors in the head at a later date. I've used ex carb heads/manifolds on injection engines several times and so had to "undo" the plugging.

Ive used tiger seal to bond copper piping across mine which is then used for the brake servo :angry:
