If you can buy Vortec heads for half the price of the World products I will take 20 sets.
The point I am try to make is I can buy the Dart Iron eagle heads or the Pro Topline heads or World products for around $600 to $635.
Both the Dart and the world heads are better heads overall.
They have thicker decks and come with valve springs good to .510 lift.
The vortec heads are thinner castings and more prone to cracks.
All you have to do is pick a set up and you will tell the difference.
