Bruny we had quite a long phone conversation about this, the gasket used was very thick, the only way we could avoid piston to head contact due to the piston protrusion on cylinder 4, i certainly have never had to use a gasket this thick before, so could never say it would 100% be sucessful, it was with your consent we gave it a go as your budget would not stretch to an engine overhaul, so we really had no choice but to try this route.

I also had various pms with you about gasket selection, where i advised you use a GRP A gasket, because of the reasons of block skimming, which is why you supplied us with a GRP A gasket to use. unfortunatley it would not have overcome our issue in this case though.

At the end of the day, the thick gasket has not worked, so the engine needs to come apart, just as it really did when we had the head off to be 100% sure it would be perfect. If you take it apart you will be able to use the GRP A gasket you have in the boot.
