Cometic Street Pro Top End Gasket Kit (.066in Head Gasket) - NA6 Miata (90-93)

The Cometic PRO2036T-066 is the StreetPro top end gasket kit for the Mazda 1.6L B6ZE engine, supplied with an 80 mm bore MLS (multi-layer steel) cylinder head gasket of .066 in compressed thickness. Cometic lists it for the 1990-1993 Mazda Miata (NA6, 1.6L). Pair it with the Cometic StreetPro bottom end kit (PRO2036B) to cover a full engine rebuild.

• Includes an 80 mm round-bore MLS cylinder head gasket, .066 in compressed thickness (the 1.6L B6 has a 78 mm factory bore)
• .066 in is thicker than the .040 in gasket in Cometic's base kit (PRO2036T), lowering compression and adding piston-to-head clearance; Cometic publishes no compression ratio, so calculate it for your build
• Cometic's matching B6 MLS head gaskets at this thickness are 5-layer; the outer layers carry a Viton coating and install dry, on head and deck surfaces finished to 50 Ra or finer
• Cometic StreetPro kit materials include MLS, AFM, aramid fiber and Armor Clad
• Sold separately from the StreetPro bottom end kit (PRO2036B); Cometic says to order both for a complete engine gasket kit
• Made to order by Cometic (2-3 week production time)

Fitment: 1990-1993 Mazda Miata (NA6, 1.6L B6ZE). Not for the 1994-1997 Miata (NA8, 1.8L BP) or any later Miata/MX-5.
