i think it really depends on the condition of the H/G, if i where you however, i would just drop the cash now, and play it safe... ARP's RULE, and the cometic H/G is equally bad ass! i would personaly make that a priority prior to putting it back together... however, again, it depends on the condition of the gasket... if you feel confident that it will be fine, then i would go for it. if i was in a real bind, and mine looked fine, i would probably reuse it.
