used 2ft of 3/8" white nylon rope fed in at BDC then hand turned to near TDC to keep the valves from dropping. Piece of scotch tape over the valve stem grooves to keep from nicking the seals as they go over it (oil them). Used the on eng valve spring compressor, BB one is different from SB (spacing is different)
