Using Copperhead Heatbreak with Prusa I3 MK3S heat sink and hot block

Hi there,

I purchased a Copperhead Threaded Reprap 1.75 (compatible with the MK3S) heat break. When installing it with the Prusa e3d V6 hot block and nozzle i noticed that the hot end of the heat break is longer than the e3d heat break by about 1.5 mm and pokes out of the hot block. Is this okay?

Thank you!
