AC Delco or Bosch Platinum. For the other stuff MSD is always good.

If you have the larger HEI dist try a HyperTech coil/cap/rotor, MSD SuperConductor wires, A/C Delco plugs with cut back ground electrodes (method on my site).

Rapidfire by far, is the best plug. NGK's fouled out far too quick. They aren't worth the price. MSD's stuff is all good. I've had Accel 8mm wires on my car for over two years now & they are holding up to the voltage of the MSD 6A very well.
