Siruda Stopper Metal Head Gasket Subaru BRZ (ZC6) / WRX (VA) / Toyota 86 (ZN6) FA20

Siruda Stopper Metal Head Gasket - Subaru BRZ (ZC6) / WRX (VA) / Toyota 86 (ZN6) - FA20

The Siruda stopper metal head gasket is a multi-layer steel (MLS) head gasket for the FA20 Subaru BRZ (ZC6), WRX (VA) and Toyota 86 (ZN6). It is made for rebuilt and modified engines where the head seal has to hold more cylinder pressure than a factory gasket.

Choose the thickness to suit your build. It comes in a 89.5 mm bore and thicknesses of 0.8 mm. A thicker gasket lowers compression and adds piston-to-head clearance, so measure deck height and set the thickness with your engine builder. The thickness shown is Siruda's figure at the combustion seal; the body thickness is in the specifications.

This engine uses a different gasket on each bank: choose Left or Right, and order one of each for a full rebuild.

Siruda's stopper design adds a stopper layer sandwiched between the steel layers around each bore. It keeps the combustion seal stable under engine vibration, and the compact seal suits engines with little room around the combustion chamber.

Note: Sold individually. Installation by a professional is recommended. Engine internals must be measured and set up by a qualified engine builder.
