BOLT LENGTH?

[SANCHOBA]

can anyone with a OEM exhaust manifold bolt measure the length from below the head? want to order some nice bolts for my jet-hot coated manifolds!
i know it is a 5/16"-18, but need a length! THIA

header bolts are shorter, since manifolds are an inch thick. I can't remember the exact length, but the header bolts are about 1/2 the length of stock bolts. I'd guess they are about an inch long or so.

I cound give you the exact length, but it's too early to dig around in the garage!

You forgot the one measurement he was looking for,from the bottom side of the head to the to the end of the thread !!!:dontknow:

Bolt Length Overall: 3.3185"
Head Height: 0.225"

LOA minus Head Height = threaded section length.


EDIT- Typo repair.
