Ok slight update, stripped and cleaned it today (well as much as i could) before any work has been done on the head and block i have noticed that the valves are already ever so slighty touching the pistons, that was with a 12 yr old gpa gasket, does anyone know the thickness of these compared to the 5 layer multi gasket, when they say 2.00mm is that the compressed thickness that they will be after fitment or starting thickness???
