Loaded yes and no.
Loaded with valves, springs, seats, keepers, studs . . . but not pistons.
The oil drainback fitting is installed, btw.
Pushrod shroud seals included- both T mod and not. Cyl base oring not. Three orings I don't recognize - and I have the Lyc seal kit - are also included. Weird. And for the life of me, I cannot find a partslist of cyl kit or seal kit that is ACCURATE. For instance, the cyl kit in the parts breakdown would have you believe rockers are included - I pointed this out in black and white to the Lycoming folks at OSH this year, they agreed, but just shrugged it off. Getting from the parts supercession manual is not possible - as the parts count doesn't match. Oh, and the mag drive cushions aren't included anywhere.
I have some confidence all the stuff is there, but come this weekend, we will find out. I'm going to at least build the block this weekend.
