Pushrod Question

I am upgrading my cam and lifters to a cam with a 284 advertised duration 320/480, and have purchased the cam and lifters as a matched set. my question is about the push rods. I removed the old stock push rods which have a small hole in the ends of the rods. I have a set of Comp Cams push rods that are the same length as the stock but do not have the holes in the ends. Would these push rods work in my setup? I will be retaining the stock rocker arms due to low funds at this time.
