didnt get any pics but it was stupidly easy, twas really easy to drill thru bent abit of coat hanger while in the hole on the old head to give me my angle when i lined it up on th eother head, first drilled a little hole, went down until it broke thru, you could feel it as it went really easy all of a sudden, then did the same with a bigger drill bit then sprayed sh!t loads of carb cleaner in there to get rid off all the metal, really easy
