Could the big end now be fooked as they must of been takin alot of the vibration whe the pistons hit ??
Don't say that haha. Its had a total run time of about 15 minutes Max so hopefully not! I'll be listening out for any rattles once I change the gasket, hopefully the heavy duty bearings bought me some extra time.

No idea I cant find the original invoice, it was a 3 layer MLS HG for the focus RS from matt lewis Motorsport. What would you recommend for a non skimmed head? There's a 4 layer MLS version which should suffice right? Or maybe the 1.8mm I've heard about.

Really? It is rather strange that its happened. They're just standard JE pistons on an unskimmed block! Hopefully this will silence the engine and the big ends are fine.
Added some more photos of the head removed too, you can see where its been making contact.
