Designed for the ultimate in engine performance and reliability, Fuji Racings 14mm/12mm Head Stud Kit is a must have component for any EJ engine build where 450bhp+ power output is expected. It is essential to have the most reliable system for clamping the cylinder heads onto the block assembly to avoid the heads lifting under load at high levels of boost. The Fuji Racing 14/12mm Head Stud kit provides this peace of mind and cuts out the expense of cylinder head modification.
Unlike Standard gaskets, Fuji Racing Gaskets have the ”Folded stopper layer” this design reduces any chance of pressure leakage from the cylinders.
Along with the stopper layer, our gaskets also have a nitrile coating to help to seal against the block & cylinder faces
Our gaskets are also stamped from dies instead of laser-cut, this helps reduce variations between each head gasket during the manufacturing process
Our gaskets are designed to fit 11mm to 14mm head bolts/studs without the need of reeming the center gasket holes out.
