I have been browsing around looking at buying a set of Gt-40 heads for my 95 bronco. Does anyone sell New Cast Iron Gt-40s?

 

Gt40 | eBay

 

The supply of "new" GT40 heads have most likely been exhausted. You will need to look for used ones. Heads sold as new may not be but simply cleaned up to look new so buyer beware!

 

Also consider that you can have brand new and far superior RHS or Dart iron heads for about $1000 a pair so paying $900 for new or refurbished GT40s isn't money well spent.

 

While aftermarket heads are a better HP option a set of stock GT40 heads may be all you need depending on what your goals are? If you can find a set of used heads in the $275-$400 range and you are only looking to improve performance a bit then the GT40 may be the best/cheapest option. A mild port-n-polish and milling of these heads will net you 20-30 HP over stock non-GT Windsor heads, Throw in a cam swap and then you will really wake up the engine!

 

You can get that just opening up the exhaust sides of E7's.
