Make sure to keep any particles out of the rings and oil system. Consult with the folks planing the head and have the block deck checked for flatness.
Correct Al head Fe block mitsubishi Mighty Max rebaged as a dodge . HG was good when I pulled the head. There is a likely hood that there was a blown HG in the past(prior to 2 years ago/ 2 owners ago) that had been fixed. There are markes in 2,3 that indacating water sitting in tthe cylinders (pitting full circle ring spacing .)
I am counting the head as cracked (without testing) as this is the only way for oil to get into the water one way(as far as I can guess) so i priced a new head at $495 from Aluminum Head Exchange in PortlandOr, my curent location. I found a Japanese "remanufactured"2.6 Mitsubishi long block. For $700 shiped ,NO core. So for $200 over the price of a new head (less all gaskets) I got a complete engine less manifolds .

cRiPpLe_rOoStEr So, what are you considering to do with that truck? Do you think it's worth to fix that engine or would you be more inclined to swap a 4G64?

2.0 may have been an option had I not found the 2.6 G54B N/A in the garage. Counting the bus ticket to pickup the miny truck in Ut drive to Mt(405mi) then Portland OR (800mi), remanufactured Motor, webber mod, and purchase price , I'm into it less than $2000 so Ithink worth the repair cost. This truck was goten as a reliable winter 4x4(sub 0f) and used to 4x4 in Utahs west desert(100mi from the nearest gas) were the soil is almost as salty as Bonneville salt flats , so will have salt rust shortly(alredy has cancer typical for age and regional os not so big of a dill )

has a fresh cluch and I'll go full synthetic fluids
