Are you talking about just the engine head bolts? If not, you need to be more specific. Not all of the bolts have identical markings. It depends on the length, diameter, location and what it's holding. Which one's and which year?

John -------- I am a little rusty on my SBC head bolt markings for 57 and 58, however, if you need any help regarding your 392 and 426 top fuel engines or for that matter, your 409's, maybe I can help. ----Regards/Joel Miller
