Hi, it's me. I think it was someone else that had the question about clearance with a larger exhaust (forget his name, he is on this board though). However, I do have mine installed and will be more than happy to take some pictures tomorrow weather permitting. If I can finagle it I will include a tape measure in the photo to show clearance. It is T-I-G-H-T in some spots, but it slides right into place and now I have some peace of mind. You will have to use a wrench to tighten most of the bolts once installed, as the larger pan won't allow access to them with a socket.
For other questions, you only use RTV for the gasket. The oil pickup tube spacer is provided with longer bolts, but no gaskets. I just went to Pep Boys, bought a roll of gasket material and made some. You could maybe get away with using RTV there as well, but I didn't want to risk having any of it get into the pump or oil galleries. The only question I had was once you install the spacer for the oil pickup tube, the midpoint attachment for the tube is hanging in the breeze. I went ahead and pulled it down with the stock bolt, one of these days I will probably pull the pan again and fix it correctly with a longer bolt and a spacer.
