thanks everyone...i ran a tap and cleaned off the surfaces with brake clean and a non lint leaving rag...i stared a new tread on my gaskets...i believe they sent 2 of the same side because on one side the 1008 is faceing up and the other side is faceing down....due to dowl postion...what worrys me is that in between the cylinders thers a metal tab that faces down,well one side faces up just doesnt look right but i may be wrong ...**** i really wanted to bolt this thing together today....
