verification of parts to the engine listed by service dept. on 2002 GMC Yukon XL Denali

If the invoice provided by a service department in a dealership describes an engine not accurate to my vehicle's true engine; would that mean that the parts listed were for an engine not designed for my car and therefore would possibly attribute to problems that excessively occurred? For example; the engine lists for this car, on the invoice: "DLR:66692 (not sure what that is...) ENG: 2.5_ Liter_ V6, _MFI, DOHC". When I know for a fact my engine is not a 2.5 but a 6.0 engine, and the vehicle is not a V6 but really a V8 AWD! Further, it was not a multipoint fuel injection but a single fuel injection, and unsure but think DOHC for dual overhead compartment; well pretty sure don't know what that is, but that going to affect the parts they will get for the car? Because a lot of the parts they matched were not able to match with what model numbers were accurate for the vehicle's model parts listed on ALLDATA.

The first thing I would do is take the VIN to the dealer or manufacturer and get the right print out for your make of vechicle
