  • Does not fit Vortec heads
Color: 551664 & Washer
They look great and they would probably fit a regular SBC head, however I bought these before I did my research. These don't fit a Vortec head.

  • Strong as OEM but better looking!
Color: 551664
These bolts replace stock small block Chevy intake bolts and look great!

  • Open end wrench applicable for headers
Color: 551664
I like these more because others have the sun head that doesnt allow for open end wrench tightening.
