lklklklklklklk. Funny you should ask if I have ever even seen a 605. I just bolted an Hd800 in to a massey super 95 for my son to run and This summer I hauled an hd605 home from kansas with the idea of converting it to diesel for my gb diesel. How do you figure a farmall lp head isnt factory? there are repops out there but the 350 and 450 lp tractors had lp heads. A picture is worth a thousand words. Tell me now, do you feel a little silly asking me if I had ever seen a 605???
