Don't think you made a bad choice using Roush cast iron heads for street motor durability. But getting talked out of aluminum heads just because of N.J. winters is bad advice. Washington D.C. winters are about the same as N.J. and I'm running TFS aluminum heads.

The major problem with winter driving is salted roads. Anything aluminum will pit from road salt if not kept clean. Aluminum heads do not present much surface area to salt pitting, although the valve covers, and other aluminum components do.

So, you rust belt guys, don't forgo advantages of aluminum heads because of old wives tails. Just keep the engine clean after you drive it.
