I'm no Chevy expert, but thought I would give your thread a little bump to give it a little more time. But, from what I have seen the Chevy guys discuss, it seems the FI heads were great in their day, but have been surpassed by newer technology, like the Vortecs. There is some mystique though in being able to say you have the double humps on your engine, for what that is worth.

Now we will let the guys who really know tell us.
