When it comes to building your FA20 motor, upgraded head studs are a necessity to keep the cylinder heads firmly sealed to the block. Added cylinder pressure increases the chance of lifting a head or separating the block. The Dynosty Head Stud kit allows for proper clamping force on the heads to block to ensure a good seal and prevent head lift on your Scion FR-S or Subaru BRZ.
Kit includes: Set of FA20 head studs, washers and nuts.
