Will 2000 heads work for a 94?
Can I use 2000 chevy vortec heads on my 94 chevy 1500
I believe so.
OBD-2 cam out with the 1996 model year. although both heads likely have the same bolt pattern and spark plug locations, there will likely be differences between the OBD pre 1996 version and the OBD-2 later version. If there are differences, you might be able to modify the later head to work with the former.
