I had to grind my passenger side motor mount to clear one of the bosses in the block. No oil pan issues. Just need to make sure you have ..250"-.300" between lower pan and the pickup when you're assembling the motor. No grinding to clearance the rods, but you'll have to space the windage tray a little bit with washers. I am using 1.8 Crane Pro Race Gold rockers and that is the only 1.8 rocker that I am aware of that won't have any issues with clearing the stock valve covers. You will have to choose a different spot for your grounds because the bosses aren't in the same place on the sides of the block. Make sure you get a new set of transmission bell housing locating dowel pins for the block before you try to put the motor in. Also, don't forget the head dowels.
