Preliminary results:

Valves were a little tight; as to be expected. Adjusted to spec.
Compression test reveals the following:
1: 350
2: 350
3: 320
4: 320
5: 350
I sprayed a few squirts of PB Blaster in each prechamber to help break up the carbon deposits before testing the compression. I cranked the engine with the injectors removed before testing compression. A dry or wet test result is up to the reader based on my method. I did not put any oil into the cylinder/prechamber, though. An oil change will be required soon to be sure no adverse effect of the PB Blaster is seen if it has entered the crankcase oil.

Cam timing pictures will be posted soon.

Injectors pop tested well and in MB spec for new injectors. 1850PSI to 1875PSI great spray pattern, no leaks. Chatter like a chipmunk.
1991 F250 super-cab 7.3 IDI. (rebuilt by me) Banks Sidewinder turbo, hydroboost brakes, new IP and injectors.
