Tech. everything is EFI Compatable. If just means tuning and correcting the ECU. I plan on doing much more than th OP and have a 93, but I also am looking into a new ECU. Or a MS (Mega Squirt) Set up but of coarse that throws its own problems in the air when using a E4OD.

Enless you can find something stating that I cant run a Piggy Back ECU to control fuel, spark, timing etc. then simply stated you can do anything with fuel injection pending you can control the fuel and spark.

I think the point is that saying and doing are two different things. After being on these forums for quite a few years, I have only heard of ONCE that someone has made a performance EFI 4.9 I6. That's only one claim to have actually done it. They didn't back it up.
So, yeah, fuel injection has lots of strengths over carburetion. That's why you don't see carbs anymore.
But as for your post above, you're speaking in pure generalities, not 4.9 specific information. Generalities are the worst way to give someone specific advice that costs time, money, and mistakes.
When you get your high performance EFI 4.9 set up and running, then feel free to guide others in their decisions.

Yes I am talking in general terms but stating that its not possible to do something with EFI is also not directing anyone in the right direction. In my original post I stated it is possible to do with EFI BUT there would haft to be mods. made to the ECU in order to run properly. So where am I in the wrong?

Well, to the OP's question regarding compression - no worries. Unless you really get silly and get the engine knocking at all rpm then the CR won't affect the EEC.
Beyond that, being possible doesn't mean practical or advisable. Unless there's a compelling reason to use a cam that's not compatible with the stock computer you shouldn't. Go crazy, port the heck out of with everything else and grab some big headers, with the right cam the truck will run fine. Bigger injectors, maybe, but we're talking about an engine that will probably never even see 5,500 rpm.
FWIW, all the pre-MAF fox-body Mustang guys I've ever seen swap to MAF or a carb when they go big on the cam. Maybe the stock EEC can be made to work (can it even be Tweeced?), or maybe you can run MS with a stand-alone E4OD controller. Or maybe you can find a MAF 300. All I can say is good luck.
Makes me glad my truck has a carb.

My only point to bring up anything with the ECU is simply.....The stock ECU is set up for optimum performance and fuel mileage with the stock specs. In order to have the optimum performance and fuel mileage after making any mods is to has the ECU redone. Is in completly nec. no advised no not really. Will your engine benfit from it yes. So really it comes down to each thier own. I do things my way others have thier own ways.
As for bigger injectors....pointless.. The stock ECU will still pulse the injector as it is a stock flow injector, which inturn will end up with more fuel than needed. Stock injectors will keep up with any N/A mod. Only time bigger injectors are needed is on a FI (forced induction build) flow on a carb is tuned much easier than flow on a injector. But if someone wants to prove me wrong I welcome the info.
As for tweeking the stock ECU yes you can. Take it to a Dyno shop.....they can either A. Flash and Reprogram the ECU or B. Burn a Chip that will have the needed. info to run. This is of coarse all depended on the ECU.

wow alot of great info here! im probably going to go with the comp 260h cam and have head milled slightly. as for porting/polishing, i might try to get a hold of a grinder and do it myself to save some money. how hard is it to port these heads? what do i do about the gaskets?

There are many vids on youtube showing how to port a head.
