Engine Performance problem
1990 Ford Bronco V8 Four Wheel Drive

I have a 90 bronco 302efi, swapt out broken moter for a late 80's 302efi, I beleive it was out of a LTD. (I got the motor for free). At first start up with cold motor it runs great. After getting to normal temp it starts to chug out and lose power and want to stall out. Could I have a cracked head? Any Ideas would be wonderfull.
