Who sells injector bungs/seats for welding into an inlet manifold?

All I can seem to find is US companies.....cheap but by the time they've been shipped they wont be.

Ill make you some if you send me some details

£25/set 4 Assuming they are to fit injectors into (accurately bored)

Or £15 set for blanking plugs.

You could pop a bit of tape on the inside and flood fill with JB weld.

Flak's will be prettier no doubt.
