I've been searching around trying to find a straight anwser to this question. I'm looking at adding hp to my 96 7afe. What i want to know is can you swap the head from a 4age to a 7afe? And also what exactly what i need to do this and roughly what hp i might gain if i do so. Or would i be better off swapping out the 7afe for a 4age

. I'm looking at adding hp on a budget, but if i need to spend the money i will.
Also how hard is it to do an automatic to manual conversion? and is it possible?
Any and all help would be great.
Thanks
