Great info, I alwasy wondered how you could tell them apart.  Oh so much easier than casting numbers.

Its not totally unheard of for flywheel to lose teeth.

The key to the exhuast port in those heads is to cut the air injection hump out, but not mess up the port floor.  I'd check them against an exhuast gasket.  You want a good match to the top and sides of the gasket.  The port floor should be slightly above the gasket.  That's the way you want it, but grinding the floor down to meet the gasket you will lose considerable velocity and flow out of the port.  The E7TE was probably the first head that had decent ports in it, which meant though you could improve it a bit by blending the bowl, working on the short side radius, trimming down the guides, etc., you could also screw up the ports by subscribing to the bigger is better theory.  When someone else did the port work I'd check what they did very carefully.  A grinder in the hands of someone want for knowledge in this department is a very dangerous thing. 

after looking inside the valve cover i found a ford emblem, 9D7 and a very large T then there was a CCP one c was inside the other c and the p was next to it. any idea what the heads are?

i have never seen or heard of a ford head with so little information on it.

i understand D is for the cecade 0f 70 then the year, i think you have been watching too much fast and loud with the winner winner chicken dinner. i enjoy that show

still as conflicted as i ever was. i really don't want to pull the heads off to look for other numbers on them. i did pull the intake and tried to use a mirrow to find any markings no luck with that either. i did find that the port matching went to the intake as well. there is a bit of rust on the push rods, i guess that shold be cleaned up before i fire the engine. i don't have a clue what the brand name is on the roller rockers and also don't have a clue how to reset them if id do pull them. sources anyone?

If the rockers are stamped, as opposed to cast/forged aluminum, the could be Ford Cobra.  As for adjusting them...with each cyl at TDC on the compression stroke, run the rocker down until you can't spin the push rod with your fingers.  The  take the adjuster nut down an additional 3/4 turn.

i think they are full rollers, they look like studs, but not screw in studs. good idea i'll get some pictures when i can. they don't look like stamped a rocker, they do have a nut with a set screw that jams it all together.

I don't know if they ever offered an aluminum driveshaft in a Fox body, but FRPP sold them aftermarket for a long time (might still).  There are also a lot of custom shops out there that sells them.  4" is pretty typical for an aluminum shaft.
