That engine really does not have an excessive amount of lines attached. Sure there are two or three which can be deleted but their function out weights their removal I think. It is not really a matter of emission control, that engine is kind of "pre-emission", it is a matter of a better running engine, driveability. For the sake of removing a foot or two (maybe) and a small device or two you end up with an engine which just does not work as well. If that's your wish then just slap on a carburetor and delete almost everything under the hood except for the motor.
