Header bolts?
OK, don't laugh, :lolg: but, what size bolts do I need for a header install?? 3/8 - 16 X 3/4 lg.? The length is really my concern, I/m 99% positive on the 3/8 - 16.
:confused:
Thanks!!!!

Re: Header bolts? (DP77Vette)
The package of header bolts I have says exactly that, 3/8"-16 x 3/4". I don't remember how much the whole package cost but I got them at a local auto store, unless you're looking for something special.

Re: Header bolts? (molchaser)
I've always used, for 35 years, Stainless Allen bolts. Tightened with allen
wrench and small box end for additional leverage, they just don't come loose.
Regular header bolts leave a lot to be desired. It's a personal preference
thats worked for me. On one or two you may have to grind the head smaller to
fit depending on brand of header you install. Besides they are nicer looking
that header bolts. Steve

Re: Header bolts? (gdh)
I just put headers on myself. The "kit" had 3/4" length. In my opinion, they are too small. I used grade 8 bolt that are 1" long. They fit fine. I checked individual holes, some of them can even accept 1 1/4". I strongly recommend using 1" length.
Good luck.

Stainless, allen head, and small diameter hex head all in one bolt with locking clips. These WILL NOT back out.
