    Spectre Header Bolt Sets are a good upgrade to those old worn out bolts. These sets come in a few variations and were designed to fit the majority of Domestic V8's. They have 3/8"-16 threads and a gold iridite coating to resist corrosion.

    46723 is rated 4.0 out of 5 by 2.
    Rated 5 out of 5 by from Spectre 46723 Header bolts I purchased and installed these bolts and they were just what the doctor ordered.I needed these bolts for their 7/8 " length. Recommended bolts were only 3/4" but with 3/8" header flange and 1/16" gasket thickness there was not enough bolt engagement. Thread engagement should always be 1 1/2 x bolt diameter at least. The only problem I have is these only come in a 12 pack. I have a big block in my 73 Z28 which requires 16 bolts, had to order 2 sets.

    Rated 3 out of 5 by from Bolts look good and did the job but the heads were too soft and rounded out too easy.
