Thanks Gaz and thanks Mike.
I've sourced a 20v gasket set from another forum member hopefully. I'll see what state the old one is in when I get to it. Best bet going to Audi for the head bolts ?
All other valves for the other cylinders are spotless.
I'm running the uprated injector kit, the orange ones I think.
I hope it's not a ring burnt out but I'll cross that bridge when I get too it.
If I need to get the head rebuilt I think I'll treat it to a wee bit porting and polishing, the car deserves it.
