Headgasket changed.. injector seal issue

Hi all,

 

Started the car up after replacing a blown HG. We’ve changed pretty much all seals on the engine with the gasket kit, and when starting up it ran fine first time. It slowly then started to run worse. Black smoke from the exhaust so we assumed over fueling.

 

Check the injectors and petrol was leaking from the freshly fitted seals we changed. When we’ve stripped it back, it looks like the seals have expanded which I can’t figure out for the life of me why? Has anyone had the same issue, and does anyone know of a reputable place to buy just the seals from ?

 

Thanks in advance

 

Oh car is 93 JDM NA model
