Integral Valve Guide (Broken Boss) Repair Options

sorry
did not know you had a magnum Hyd roller and factory MPI
WHAT YEAR COMPUTER which truck
what gears? OD trans?
I have the 92-95 one and it is a POS
That hughes cam is to big for you tow/ haul 0-5000 usage
figure your compression ratio with the new heads
with a couple of different gasket thicknesses
if under 9:1 think of the short Howards
Hydraulic Roller Camshaft; 1992 - 2002 Chrysler 5.2L - 5.9L Magnum 800 to 5000 Howards Cams 770225-14 | Howards Cams
with the shorter duration you can squeeze the lobe centers somewhat
but you need to explore carefully with factory computer
figure out what you are going to fix the heads first
do they have a modern multi angle valve job
valves back cut
etc
lots of good options suggested depending on your budget
SlantSix64 put a regrind in his and it worked out well but that cam might be too big for you
There were several one is the MP RT cam and another is called the "sausage"
both are too big for what you want to do
an early 5.2 cam would work or just use the stock 360 cam- this is a 360 or a 318? oh sorry
5.2 or 5.9>
