Hey Eric: Someone posted on here a week or so ago that the only true Vortec heads have this sawtooth pattern cast into the front of the heads, where the old Fuelie heads had the double humps. What's with that? My heads are Vortec, and they don't have that, nor do any of the ones I looked at in our parts dept at work.

And if I can ask (not trying to hijack, but it is along the same lines), my heads are these, and I pulled them up on Mortec. Can you tell me anything about them and how good they are. Not looking for out and out HP, just usable heads.

Thanks, Don
