The best thing I have ever found for eliminating dry starts is running Lucas Oil Treatment. Its in everything I drive and has been for years. And since I have never blown up a engine in my life its not harmful. Its very clingy and coats everything. Even non moving parts like a distributor, when you pull it out you can feel the film with your hands. It might cost you a HP or two but IMO its worth it.
I would highly recommend using it on engines that sit a long time. Many of our Pontiacs are engines like that these days.
When I started up my first roller cam engine that was all that was on the cam and I dipped the bottom of the lifters in it (after soaking in oil all night)
