Hi, first post. The long short is i swapped an om617.952 turbo into a 1983 toyota 4x4 long bed. I pulled the head due to a leak in the #4 exhaust valve as per my leakdown test, or so i thought. The machine shop just called and said my head is cracked all over the place. They have two earlier heads they would sell me for cheap, but it sounds like they have different glow plugs and he isnt convinced they will work. Does anyone have experience with this? Or know a good source for a non cracked head i could get sent to the shop for a rebuild? This is tricky because the truck is in kansas city, and i now live in maine, so i was planning on flying back to k.c when head was done, installing it and driving it home. Thanx
