Spark Plugs for Vortec heads.

What kinda plugs you guys running with the Vortec headed 350's.

Some Details on mine, 355 10.5 compression, XE 274 Hydraulic cam(230/236@.05)

Anyone with anything similar, what you running and why.

I'm running the stock plugs for no better reason than why not. I haven't burned these up yet. I could go with a hotter plug, but I don't think that they make a big difference. I'm running champions at .040 gap, on my Accel ign.
