Both are about the same as much as flow possibilities. Depends on what valvetrain you want to use.

i have a f-303 cam going with an rpm airgap intake. and i have already finished the porting of the exhaust ports and about to start on the intakes. i was worried about the size of the combustion chambers dude these things are huge and i think they are the 74 and up heads because they have about the same valves as my e7's (i think!!) just eyballin it. i was worried about the compression loss. but if i can gain more with the flow capabilities i can deal with it. im just wondering found alot of mismatched stuff on other websites. some say their ok some say they suck. others curse and throw hissy fits.

The big chambers aren't gonna help you. I would scrap them and get the money from recycling. E7's are not really so bad with some work, but it's very difficult to hand-port iron heads without at least letting a machine get the bowls bored out some.
Why not buy Preston's Edelbrock aluminum heads with all the rockers on for $900? That's a steal!

if i had the money i would have already snached his arm off. i have a set i got for free that came off a 306. the guy i got them from said they were portmatched e7 that were ported to match my f303 cam. well i set my stock e7's down to compare and then figgured out they were compleatly diffrent heads and i figgured the combustion chanbers would hurt me. but yea and im doin all the port work myself.
if i had the money i would have already bought the heads from preston i just cant afford it right now

So... someone told you some D8 iron heads were "ported to match an F303 cam" ??? First, you should probably not deal with that dude anymore regarding cars and second, just have a cylinder head shop do your E7's with a valvejob and some better valves and springs. Then you can grind the EGR bump off the roof of the exhaust port and run the heads until you can afford others. E7's are not worth going after with a burr bit and grinder unless you have to have STOCK heads for class racing...trust me I've done them.

Please ask him to join this forum and explain to us how a head can be "port matched" to a cam.
