no specific modifications needed to run alky.

Here is my opinion on their performance. Depending on what kind of power you are trying to get out of them I think they will work great as far as being an out of the box production head. But, in my opinion they wont make as much HP as Iron Eagle or Sportsman heads due to the smaller runners. As I have been told that alcohol likes large runners... on the order of 215-230cc for a 377. The Vortec i beleive are 180? but not sure.
On the plus side.. If you run in a claimer class the fact that they use a different intake and valve covers may discourage some from claiming you.

Dont get me wrong I think they are a good head and if you have them I would go ahead and use them. But if it was a choice between going out and buying Vortecs or Darts i would go Dart any day. By the time you get new Vortec machined for springs to take over .450 lift and install s crew in studs, and get the right intake, springs etc. you have spent nearly the same as Dart heads that can be bolted on.

We already have them, they just need some work. about $450.00 worth of work. However we are not in a position to buy new aftermarket ones at this time. I sure hate to spend the money if it is not going to make a difference. Thanks for the information. This is the start of our second season running modified so it is a learning process. Modified is surely a world of its own. Thanks for the help.
