Yes, get a hold of Mike. I had the same deal with my W2 econos. Mine were so off that the rocker arm was hitting the retainer and the roller was just about off the valve tip. I had the correct rocker shafts and the 1.5 ratio blue MP rocker arms. The shim kit helped dramatically. My W2's are late 70's vintage and I'm pretty sure the MP and Crane stuff, even though everything says that they'll fit, is actually meant for the race heads, especially the long valve versions.
