Corvette Heads

I'm planning on swapping the stock heads on my L98 for a pair of ported aluminum L98 heads. For those of you who have done this, what should I expect? What are some of the things to look out for?
Thanks

The center 4 intake manifold bolts are at the old style angle.

thanks for the info guys.
For the EGR, do you think I would be able to hook up with the cast iron exhaust manifolds? I'll have a machine shop take care of the angle of the bolt holes for the intake.

Your compression will go through the roof as well. your heads have a 64cc chamber and the Al L98 heads have a 58cc chamber. Thats why they work so well on 305s.
