Looking thru quickserve part numbers it looks like the piston and liners, cam, and injectors are the same but the head and turbo are different. I can understand the turbo being different but what’s up with the head being different?
I’ll take some picks if the intake side of the head for you guys. You literally can just barely make out the valve stems from the packed in carbon at 583,000. I don’t know how it was running. Lol
Yes replacing trans with a rebuilt 2050 18 speed. Just hope rear ends make it a while. Lol
I believe the head has more pressure on the valve steams also. Another thing is you better cut the counter bores and figure out how to get a better shim in there. The factory dimensions on that shim are a disaster waiting to happen. Not wide enough in my opinion. If not accidentally installed perfectly you could have very little contact between liner and counter bore shim. I say accidentally because there is no way to know if it right or not. You can’t see anything there after it’s installed.
