PROFORM Wedge Locking 3/4” Header Bolts for GM 396 to 502 Big Block Engines except for 348 and 409 Engines.

Eliminate header bolt backouts on your GM 396 to 502 Big Block Engines except for 348 and 409 Engines with the PROFORM Wedge Locking 3/4” Header Bolts from CJ Pony Parts! These bolts use a wedge-lock system achieved with super-hardened external teeth that grip the bottom of the bolt head and top surface of the header. This unique lock style is more effective than traditional bolts, employing the power of tension instead of friction for a solid hold.

Features and Benefits:
- 3/8”-16 Thread Diameter
- 3/4” Length
- Wedge-Lock System
- Reusable
- Set of 16 Bolts

As unrelenting as the hold is, the bolts can be removed with a normal wrench and, with a little lubrication, can be used again and again. Complete as a set of 16, this hardware update will provide a solid layer of defense against backouts caused by day-to-day driving!

Please Note: These Bolts also fit Ford 5.0 and 289/302/351W small block engines.
