Freestyle removing x scream power valves

[sqwidget]

Im trying to remove the power valves fromy ss865 motor. The power valves are getting hung up in the cylinder somewhere. How do you remove them?

they should slide out sounds like ur motor was assembled withnthe same length head bolts all the way around, the head bolts over the power vlaves need to be slightly shorter, back them off and the power valve will slide right out, i had the same issue
