It does have mushroom lifters - my mechanic seemed to be very aware of
that fact but I didn't understand the ramifications.

Maulesitter,
You do not need to pull a cylider to look at the cam.
Just pull the rocker arms, push rods, tubes and lifters. You can peer in
the hole with a flash light and mirrow.

Unless it's one of the few Lycomings running around with
automotive-style barrel lifter bodies, the engine has mushroom lifter
bodies. The portion that rides on the cam lobe has a larger o.d. than
the rest of the body (and the corresponding hole in the crankcase).
