I ran an eight row 30" head on a 1460 the last two years. It worked but I was in 160 bu. corn and the hopper was too small to get very far without waiting for the grain cart to get back. This year I went to a 12 row planter and a 6 row head. Will try that head next week. By the way both heads are Masseys. One other comment, you have the Massey heads already and you can do what I did. Get a Bish adapter and use them on your IH. I can't believe how well they work together.I did have to pitch the face plate up one hole to level the head but as a plus, they're both red.
