If you said chopping head you would be out of luck but I think you will be OK. You may want to get the cast pulley on the end of the feeder house to replace the lighter duty one that may be there now. I had to replace that pulley to drive my 12 row chopping head but I gather that my header is the biggest one safe even for the cast pulley. I have the standard feeder drive I think it's called.
