I've noticed that small block timming cover bolts, and oil pan bolts appear to be the same as the 348/409 bolts, but what about intake manifold bolts? Does anyone know if big block intake bolts would be the same? I'm using 817 heads and a 340hp 409 intake manifold. Any info would be appreciated. I'm trying to save a few bucks and avoid buying the "specialty" 348/409 parts.
Thanks
