Might be 9 to 1 depending on deck height and gasket used. In any case, not enough compression for that camshaft, IMHO. I've never even tried one below 10 to 1 compression, most were 10.2 to 10.4 to 1 or so, and we prefer the 60243 for manual transmission and any more compression than that.
+1 on the 4 keyway set, could have moved the cam just about anyplace, at least from what I've seen here with those set-ups.....Cliff
