According to my '96 FSM they are the same:
Diameter Intake = 1.916 in
Diameter Exhaust = 1.624 in
Length Intake = 4.893-4.918 in
Length Exhaust = 4.907-4.932 in
for both the 3.9L and the 5.2L engines - that info along w/them stating the 3.9L
design came from basically lopping off 2 cyls from the indestructible 318 makes
me think that the port sizes/shapes would be the same. I am told the templates
are labelled for individual cylinders? Anybody know?
