Differences between 89-93 heads from 94/95 heads?

I have the oportunity to purchase a nice 94 SC with bad head gaskets

This is my question
I have a SET of ported stage one DR fred heads with cam and intake that was intended to go on my 90 SC Im thinking of selling my 90SC and buying this 94


Would the older heads/ cam /intake be a direct bolt on to the 94?

Would putting an older head onto a newer motor raise/lower compression?

Thank you all for any help I get
 
Performance wise they are the same,,teh later models may have slightly revised water jackets if I remeber ciorrectly..Wouldnt make a difference
 
I believe it is a deck height difference, however the heads are interchangeable. The head revisions were meant to help with the head gasket problem (I dont know if they did or not)
