These are custom built for nitrous with the special nitrous ring built inside the gasket. They are 42 thick. I paid $230 for these. They were bolted on the engine but never run. Cometic Inc...says they can be reused numerous times. They will hold massive cylinder pressures.....ideal for nitrous, supercharged or turbo set ups. I have to go to a thicker gasket so these will not work for me! I wish they would!!!!
