That will do what you want. Depending on where the idler is (normally on the trailing side of the belt) you will need to advance or retard the cam timing. Certainly it should give you more adjustibility than a fixed key. Finally, don't forget to check your ignition timing after you adjust it. I don't know that engine but on some (honda for example) they take the timing off the cam so you MUST set the timing after every cam adjustment.

Hope that helps.
