Nice! Is that a steel valve cover I see? May have had an engine swap at some point? Lots of little tricks out there to make those 4.2's wake up a little more .

no i do not have a swap in mind but want to lift at some point but idk i like lots of power

May have worded that funny, lol, meant it already has been swapped, for an older engine (and or head). Not a bad thing though, the plastic covers suck.

I read in a tech article once that the later 4.0 head practically swaps directly onto the 4.2 block I think the only thing that needed to be changed to make it work was the pushrods. Gives a bit more compression and better breathing I think they said it's worth 25 horsepower with no other mods.

I could be wrong on that though... But it's worth looking into if you want a bit more power without doing an engine swap.
