98 Chevy S10 Misfiring Problem

I recently replaced my intake manifold gasket. I forgot to mark the distributor when I removed it (well I didn't know you had to, and my dad (he was helping me, he's the certified mechanic, an HVAC mechanic by profession) forgot about it) and so the timing got messed up.
