I notice jobbers offer "sizes" when looking up 292 chrome valve covers. they reference 3 in and 4 in Chrome Valve Covers. do these sizers refer to the length of the studs from the edge/ledge of the head where the cover rests to the top of the threads? Some suppliers just list one part number. My exisiting valve covers are about 3.5 in tall. Thanks in advance
