HKS 2.0mm Stopper Headgasket

The only head gasket I recommend for building a 7M, the cometic, TMS, and stock head gaskets won’t hold up to extra cylinder pressures because of their bead type design.

This HKS Stopper type is highly effective in sealing because it incorporates a stopper instead of a grommet or bead which can become weak over a period of time. The stopper type consists of the most number of layers of plates for a better seal. The better seal is caused by the stopper on top of the bead or grommet. The increased sealing capability is also due to a molded stopper ring around each combustion chamber. This stopper type is the most expensive of the three types of metal head gaskets.
