    100-1109 is rated 5.0 out of 5 by 3.
    Rated 5 out of 5 by from nice small head.easy to get a wrench on these header bolts worked great. I had some pipes that were very close to the bolt head, so the small heads made it allot easier to get a socket on. I'd use these again

    Rated 5 out of 5 by from Great fastiner as expected from ARP The smaller head configuration is a real life saver for both intake and exhaust manifolds where tight locations make getting a 7/16 or 9/16 wrench on fasteners is a no go. They are built strong so they dont strip. Great product!

    Do they make the 3/8" bolt with the smaller head in a 3/4" length instead of 1"

    will this work for a 95 firebird formula 5.7 LT1 V8 with long tube headers?

    Asked by: DPack96
    This will work on the 5.7 with headers up to 3/8 thick at the flange.
