Got the part number ? RS gasket is defo 0.6mm thick, Ajusa do a RS gasket and it’s 0.7mm but that’s the thickest I could find that cross ref matched fords part number,
Fords ST170 gasket is 100% thicker than the RS one, the thinnest st170 gasket I could find is 1.2mm also made by ajusa......
Doesn’t sound like you were sold a RS gasket tbh
St170 4 later is a a much better gasket to use imo as it has more “squishy-ness” about it to help seal
