I've researched about swapping the 4.0 head on a 4.2 motor for increased power. Just interested in knowing if I would get the same benefit just to get the 4.2 head ported so it can breath better. Read where the 4.0 has a 45 degree flow compared to the 4.2 90 degree.
Thought that reworking the orginal head might save some pennies and have better, form, fit, and function than the 4.0. Read where some were having problems with the water jackets leaking after the swap.
Any info is appreciated!
