--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.

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.

Oh you mean like the $600 pair of GT-40x aluminums? Is that what's called doing your homework? Those 320cfm+ heads are not just ported. They have CNC work, custom valves, and the whole works thrown at them. That is not a "port" job. The stage 3 port is gonna get you about 290-300cfm intake, and 220-230cfm exhaust.

I'm sure you've done a lot of research on the GT-40x heads? Maybe you notice an extreme deficiency in flow somewhere? Called the exhaust side with less than 70% of intake flow? Not only that, but they don't flow much more than a stage 1 GT-40P head intake wise, and less than the stage 1 GT-40P head on exhaust. We're talking 10cfm more intake, and about 10cfm less exhaust. For only $600 more.

My only experience with Ford tech people is they don't know their products real well.
