August 25, 200817 yr 1987.5 MPFI EA82 XT i've done EA82 head work and head gaskets before but it's been awhile and I've always reused the same heads (i think so anyway?). doing this XT again and this time i'm installing two new heads. but they appear identical and I don't have any other heads to look at. how do i tell which one goes on which side? all they have that is different are numbers on the bottom "23" and "25". everything else appears identical. i'm wondering if the place i bought these from sent two heads from the same side? i hope not, that would completely suck.
August 25, 200817 yr They are the same. The turbo heads are right and left. The other models are interchangeable.
August 25, 200817 yr ...The turbo heads are right and left. ... Yes, but one can be made into the other, by either tapping or plugging the coolant and oil bosses. +1 on them being the same on non-turbos.
