My post was replying to mkuhns question, however from reading through your posts a review your current loader hook up may be in order to clarify things. A complete description of what your loader and plumbing is may help clear this up. Does your 37 loader have single acting lift cylinders? Do you have a hydraulic bucket with double acting bucket cylinders, or a trip bucket (no cylinders)?
Does your loader have its own control valve?
You posted the loader is connected direct to the SCV. Do you use the SCV lever(s) to work your loader function(s) through hose(s) from the remote couplings at the rear of your tractor, or does the SCV lock in to supply the oil to a loader mounted control valve and accept the return oil from said loader valve through hoses attached to the remote couplers? If you have single acting cylinders using one hose from one remote coupler, lifting and lowering controlled by the one SCV, that one hose is both supply and return, so using the ported filter cover would not apply. Unless you install a loader control valve, plumb it separate supply and return hoses, and stop using the SCV and remote couplers.
What has been suggested to you (and mkuhns) is that for best operation of a loader the oil supply should come from a tee, in the pressure line ahead of the SCV, to a loader mounted control valve. Then the return oil from that loader control valve should be returned to the ported transmission filter cover. This is what is shown in the parts drawings Tx Jim posted for you. This plumbing arrangement eliminates using the SCV(s) and remote couplers. The parts catalog also shows one hose from one remote coupler, controlled by the SCV, to the single acting lift cylinders, for a loader without bucket cylinders.
If a loader mounted control valve is used it must match the type of system. Your 1020 is a closed center system so the loader control valve must be for a closed center system. (And single acting cylinders work better if a double acting valve is not used.)
If I'm wrong, hopefully TX Jim, buickanddeere, or someone will correct my errors.

Today's Featured Article - Show Coverage: Godfrey, Illinois Country Days - by Cindy Ladage. Except for last fourth of July's Old Gold show in Springfield, Illinois, I don't remember when it was so hot. Nevertheless, the heat didn't keep vendors and visitors alike from enjoying the third annual Country Day's Event. Jane Elliott said the event was originally a one man show. "Barry Seiler, owner of Country Town Farm Supply store used to invite people up to the Johne Deere store. He would give hats and a free meal for everyone that brings a tractor." Elliott said while this
