alright! now that I just helped answer a question about correct valvetrain geometry lets see what happens when everything doesn't jive just right...
from what I understand my problem appears to be the length of the rocker stud, as I might not have enough threads under the poly lock.
this happened at 6,500 RPM... imagine the look upon my face when I heard it go.
luckly the valves seem to be just fine, haven't had time to do a leakdown yet.
