Tick Performance solid-dowel pins are necessary when upgrading to 1/2in head studs. See the recommended product below. 

 

Cylinder Head: 

After performing the job on the block, you can use the DIY Head Fixture on the heads to make room for the larger studs. Bolt the fixture to your head and use the larger, 33/64in drill bit (included in the kit). This will provide ample room for the new, larger 1/2in studs. 

 

IMPORTANT:

The Tick Performance DIY Head-Stud Upgrade Fixture is designed to work with the Tick Performance ARP 1/2in head stud kit ONLY (GEN-IV or GEN-III). The fixture and instructions may not work with another brand 1/2in head-stud kit.
