I have been looking at this.. so I can install an ecotec 2.2 into my alfa romeo spider.. there are a lot of options.. while looking closely at the block, I am thinking cannot I just tap the oill feed hole below the left and right back after you remove those 2 allen plugs and tap out the 2 oil passgeways to the balance shafts, with a allen set screw of the correct diameter. and machine off the balance shaft at the front?
