Have you looked into the MAST heads?
But other than that, I'd be a TFS fan my self.

For a 440 sized motor, the All Pro heads would SMOKE all the others.

We use TFS nearly exclusively at Tick for 99% of our heads cam builds.

There really isn't a head out there that out of the box has the mid to low lift flow these heads do aside from an AFR, but the exhaust flow is what separates the TFS and AFR heads from the start!

well, i personally believe TFS have good reliable results, here some more info, this is a light car, mustang weighting 2700 lb. 440 ci, should choose a pair of heads with something more than 245's some heads with a rect port maybe?
thanks

Do you already have an intake? If that is still an open option I would take a look at some our PRC Aftermarket casting LS7 heads. They are a completely aftermarket cnc ported LS7 casting with a 6-bolt head design. We offer a 285cc runner which moves huge air for the larger cubic inch motor you have. Take a look at this link and if you have any questions feel free to get a hold of me.

It was Brian tooley but those where not untouched heads. He use to own or be involved with tea. Here's a link.

LOL, Ill talk to the boss and see what I can do. I can't promise anything for free but it would be nice for you guys to see what we are capable of. I think you guys would be very happy with the quality and power our aftermarket casting line delivers, whether its cathedral or rectangle.
