I'm no expert, but many experts have advised me along the same lines that a performance coil is nice however getting a billet distributer is essential for dialing your engine in for max performance and efficiency. I was told to go with either Mallory or MSD. The price was high in the new market, but I came across a like new Mallory HEI billet distributer that included the cap, rotor, hi-voltage coil, and heavy gauge wires within weeks of looking for $100. The guy told me he was an "MSD guy" and just didn't prefer it. The deals are out there on CL just know what you're looking for and pounce on the opportunity.
