what [stainless ?] bolts are you using on your engine, and what manufacturer are they ? i intend to paint the replacement 446 for my charger the same color turquoise, and use bolts like you are using.
Almost every bolt on the engine is from ARP. I just measure what I need and order accordingly. It sucks when you need 6 bolts, and they come in packs of 5, but that is what it takes sometimes.
