A6 Cam Shaft or D16A6 Head?

So I have a D15B7 full stock in my EG and a D16A6 from '88-'91 CRX with a '92 Civic SI transmission. It also has the PGM-FI. Should I swap the whole A6 head onto the B7 or just the cam shaft and get an adjustable cam gear to correct the timing? Should I also swap the PGM-FI onto my B7 along with the A6?
Any other parts worth swapping from the A6 to the B7?
Any info would be appreciated.
