Totally Dissapointed!!!!!

Been there as well. It doesn't help when a shop treats your motor like it has coooodies.
The stock distributor is fine and the MSD is a waste of money at this point. If you need it upgraded, ethier re-curve it or get a MP unit with an adjustable advance.
A baffle (or set of) inside the valve cover is a good thing to have. If not there, the oil gets sucked up into the carb and down the intake over the valves crating a mess and killing the air fuel mix.
Baffle the valve covers.
