It may be considered valuable or not. If you visit a program that doesn't care about research at all and you insinuate to them that you must go to a strong research program they may wish you good luck when it comes to the match.
The real question is - do you want to do research in residency. If so - attempt to pursue research heavy programs and they are probably more likely to value the work you have already done as a testament that when you tell them you want to do research you aren't pulling their leg.
Programs would like a lot of things from you. Personality (pleasant to work with), Hard worker (reliable, non-complainer, part of the team, intelligent (teachable, wants to learn, strong foundation). Work to demonstrate and maximum all of your good attributes.
