seems the price of the bolts was 40 or 50 dollars for everything. does it pencil out cost wise, not much considering a head gasket is about the same price. are they needed? some would say no, but i ran a lot of nitrous and thought i had lost the head gasket after 2 years, but turned out to be the water pump shaft. might have had the same luck on stock ones, but i do know the heavier ones work
