    I'm getting a complete new exhaust installed, and definitely want to use the grade8 locking header bolts. Only problem is, I don't know what size bolts I need.

    I've got an '84 blazer with a SBC 350. Do they all use the same size header bolts? If so, how come http://www.stage8.com has multiple part numbers with different sizes listed?

    Can anyone help me out here?

    Thanks,
    Thomas.

    Yep, those are them. Will p/n# 8931 work?

    I looked a little closer, and it seems the only real difference in the SBC bolts is the length (3/4" or 1") and the material.

    The 8931 is a 1" bolt with a 12 point head on it.

    Also, anyone know if any of the chain stores carry these? Pepboys, Autozone, NAPA, etc ...

    Thomas.

    Thanks. I ended up ordering them direct from Stage8 and overnighted to the shop.

    Spoke to John over at Stage 8, great guy to deal with. He really helped me out.
