First off, I hope from now on people will read the entire thread before posting a reply.

--Unit 5302: I know the TFS heads flow 255 stock, BUT you can send them out to get ported to 320+ cfm intake, 235+ ex.
(http://www.bennettracing.com/products/tfstwisted.html)

That is a good thing becuase you can stick with the stock casting now, then if you wanted to build a 351,408, or hi reving 302.347
you can send them out to be ported for $1200 instead of spending $3500 on a head that is comparable.

And for the wieght thing - You will drop 25 lbs PER head. Thats 50 lbs removed that was once hanging off the front of your stang. Not only will it help in acceleration (not much, but every .05 counts), it will aid in wieght transfer which is more important.

I'm not trying to be a smart ***, but its a pet peeve of mine when people don't do thier homework first.
