  These heads are a great choice and at a great price, you will not find this kind of quality for the price we have them listed at. Perfect for everything from street, marine, and in any other performance/race application where a quality head at an affordable price is desired. A great upgrade from OEM factory heads. They should handle up to about 550HP in as-is form without much problem. Further gains can be had with gasket matching and porting techniques. Please note the intake port size, this is larger than most Ford intakes have so some port matching may be required.

 Aluminum material allows the benefit of higher compression ratios on the street compared to iron heads, not to mention how much weight they save compared to the factory cast iron ones!

We also carry these as a non assembled bare pair. Check out our store for more cool products including other head selections including the 210cc port version!
