1994-00 factory head gasket

The factory head gasket for 1.8 Miatas is pretty tough. So here you go, an OE Mazda head gasket. Suitable for up to 1.5 mm overbores, 0.032" thick. Multi-layer steel (MLS) construction. Mazda part BP26-10-271

The coolant passages are different on the 2001-05 heads, so the gasket is slightly different. If you're mixing and matching heads and blocks, match your head gasket to the head you're using.
