... I broke the bolts that connect the intake to the exhaust. They snapped off at the top of the exhaust side. ... I broke the stud on the very first spot at the top.

You certainly aren't the first to snap the long bolt in the center which bolts the intake manifold to the exhaust, since usually old and rusty. I recall using a stainless steel bolt from Ace Hardware for that, or a grade 8 yellow-chromate plated bolt might be a good choice.

When you re-assemble the intakes, carefully read the article that SSD linked. The triangle and cone washers install opposite to what most people would think intuitive. If you install them flipped over, the exhaust manifold can eventually crack, as pishta said.
