4.6 DOHC swap

what all needs to be done to drop in a DOHC engine in place of the SOHC in a 95 t-bird, or would a head swap be better???

also can the PI head swap be done on engines prior to '96
and what is all involved in this?

do all 4.6's have aluminum blocks

Sorry for all the ?'s but i'm new to the modular world so be thorough when you explain

thanks

The 4.6L block comes in both iron & aluminum.
