Dowel Pin features include:

• 1. These dowel pins allow you to run a VTEC head on an LS (B18A or B18B) and B20 (B20B or B20Z) blocks without drilling into the VTEC head.
• 2. Most people use a 9/16" drill bit rather than a 14mm drill bit which allows the head move around causing slop and misalignment.
• 3. Allow adequate clearance for ARP head studs.
• 4. CNC machined
