Spark Plugs & Ignition Coils for 85 CB700SC

Hello fellow Riders . . . Any recommendations on spark plug and ignition coil upgrades to improve startup and performance on an 85 CB700SC.  I've read that later model bike pkug/coi/wire combos make a big difference.  Thought I'd check with seasoned vintage riders for advice on this first.  Allready saved a grip of cash with sound Shinko tire advice. Thanks in advance for your responses.

You cannot beat the GM HEI coil pack mod. Cheap and easy to do, and gives a really hot spark. There is a write up on here somewhere about doing it.
