you mean you removed head with injectors still in it ?
Plusgas, Heat, and jam the head against a wall between a wheel (still on the van)with lots of cardboard to protect stuff and use an impact gun rather than a breaker bar perhaps

No head still on the engine put some brake fluid around the injectors (my dad swears by it as a penetrating oil ) would be very nervous about using an impact gun would crack the head I'd imagine (might experiment on the cracked one ) am even very nervous about using a breaker bar got a reply on another post in mechanical about having the engine as hot as possible so will try that thanks though Aidan

Sorted got them out by running engine hot then removing them looks like flame traps weren't sealing properly a lot of carbon on the threads which didn't help fresh ones all in and coated with copper grease to stop them seizing in the future :ok
