I had never pulled a cylinder either, till another member convinced me I could delete the base gasket on an 044 or 440 w/o any other mod to the cylinder. I did not think so, cause the gasket is supposed to be 20/1000. He told me it usually only changes is about 16 or 17/1000, and he was right.
044 #1 and my MS 440 both have base gasket delete, and both run very strong w/o any porting. Conversely, you usually can't get away with doing that on a MS 460, the squish will be too tight.
