ok, so the stupid little check valve problem is going to make me change the IP head;. my question is do i need to have the whole pump sent to a pump shop to change the head or can i just have the mechanic (8 yr duece exp) change the head making sure things are timed/ aligned right

Changing the hydraulic head is a pretty simple "by the book procedure".
The R&R procedure of the hydraulic head for the ld, ldt and lds are the same.

For your LDS465 engine, basically:
1) Remove the steel lines to the injectors
2) Remove the cover for the fuel cut-off mechanism
3) Remove the fuel cut-off lever (be careful with the "tooth" at the end which is loose)
4) Turn engine over manually until a scored gear tooth (may be marked in red) is lined up with a pointer visible when the fuel cut-off lever is out of the way.
5) Remove all fuel line connections and 4 ea nuts clamping the hydraulic head.
6) Pull hydraulic head straight up, you may have to tap it lightly. Reverse procedure for installation.
I just finished working on mine and it's pretty fresh in my mind.

yep pretty simple, just be sure the pointer aligns with the marked tooth (under the shutoff cover) before you try to lift the ip head up. this is the only position it will come out in.
