Quote: If you do need to change the springs there is a tool available that allows you to leave the head on. With it you end up changing 4 springs on 2 different cylinders at the same time. It only takes about an hour to change all 16. Mancini sells the tool.
Rule of thumb: If you're running a 5/16 fuel line, you only need a single spring. If you're running a 3/8 fuel line you need a double spring. Oh, and don't forget to line up the dots on the springs and retainers otherwise your spring timing will be retarded.
At this point I'd rather take the engine out and get rid of the trw 2232 pistons and buy some eddy heads.
