I Need Help Identifying These 4v Heads.

I picked them up pretty cheap, I know that the "B" heads are not very desirable but since I was building a 2v stroker I thought any 4v would be an improvement for breathing. What I'd like to know is from what car (Lincoln, Mustang) did they come off of. This will help me select parts to replace such as valve guide, seats, srpings, etc. Here are the numbers I pulled off of it:
Cams: F55E-6A270-AA (23M0153J0 & 23M0153K0)
Cam Retainer: F2LE-6B277-BF
Valve Cover: F50E-6582-A A (F2R)
Can anyone tell me what car these are off of or tell me how I can identify them?

Thanks!
Jim
