Q:
Does the nickel plating provide anti-seize characteristics when these bolts are installed in aluminum heads? Can you advise best bolt length for installation of the Doug Thorley Tri-Y Headers on Edelbrock AMC aluminum heads or does the length need to be calculated by measuring header flange thickness, gasket thickness and thread depth on the actual heads?
Asked by:

A:
Regarding anti-seize, we always defer to the manufacturers instructions. For the length, the Doug Thorley flanges are 3/8" thick, and you need to add that to the thickness of the compressed gasket, and the available depth of the hole in the cylinder head.
