if it were me i'd get a set of MPH 2.5 heads. VT engines, & Fox Lake also have good stuff as well

"New" heads are simply factory Ford castings that are ported/polished by an aftermarket company.
Well...not to beat the subject to death...but do you guys think its possible for me to port/polish my own heads with my friends dad (ford guy currently building a stroker motor for an old fuel injected 5Liter...)do all of the mods I suggested in the beginning...plus the existing bolt ons I already have...and hit 320ish???

i wouldnt..
porting and polishing is from what i understand an extreemely precise deal. Its not about making them the biggest ports you possible can.. there many other things to take into account that an eye and hand cant

Hmm...what about the whole "polishing" part...?
What exactly does that mean anywayz?
Most of the popular shops like VT and MPH get their heads from Fox Lake.
Ron is a great guy over at Fox Lake and is very knowledgeable. Fox Lake does not polish their intake runners or exhaust ports. And to the best of my knowledge, most shops that re-sell Fox lake ported heads do not touch them either. Some shops that hand port their own heads without using a CNC machine will fan roll the intake runner and exhaust port as the final touch, but even fan rolling is not a polished finish.
If you see 4.6 2 valve heads that are advertised as polished, you probably want to stay away from that shop. Nobody in the know actually polishes a fuel injected head. You want the intake runner to retain the very small CNC cuts. It keeps the fuel in suspension.
Please don't attempt to port your own cylinder heads. Porting cylinder heads should ONLY be done by the pros who know what they are doing. It's a vey complex process and the port geometry involves some in depth calculations. You can quickly ruin a head with a dremel.
