99 Exploder 5.0 Longblock compatibility

Pardon my loss of knowlege but I am about to buy a longblock out of a 99 series Explorer. What am I going to need to make this thing work?

I have heard the heads are different and require special headers. Will the explorer factory headers work? Are these heads aluminum or Iron?

Cam, does it suck real bad or is it comparable to the 5.0HO cam?

Thanks, and I'm sorry about the newbie mistake of posting something so stupid. I'm so used to calling an explorer and exploder that is what I searched for and didn't find much.

I'll be running the Edelbrock Intake I think, I'm not sure if it comes with the intake on it. Sometimes they come with the intakes and sometimes not. I hope so because then I can sell one of the intakes.

Yes I have to pass Emmisions, but I can probally do it with the stock H-pipe I have.

I want to do longtubes but don't know if that would be good for emmisions, so I might get some shorties then longtubes later.

Because I have to pass emmisions, I might leave the stock cam and all in there just to get it running, and pass emmisisons, then I will pull everything and make a little HP. Because my car is so torn down, all I want is something to get it moving, and get some of the bugs worked out, then it will be time to start putting some twist down the driveshaft.

Thanks.
