Cylinder cooling fins often break from being pried on during head removal.
Are these supposed to be new cylinders? With all the heating problems these
engines have, missing the top fins is not good. The head damage was caused
by incorrect valve guide removal. The guides were driven out with a punch,
hopefully by press, not a hammer. As the guides get pushed out, they
mushroom out and then the hole in the head gets messed up. If the new guide
is properly centered and it seals properly, it shouldn't be a problem. Knock
off the broken pieces??

The local shop halted during the install of my new rebuilt AVP 2.0 motor
when they saw something funny on the heads.

I don't know how quite to explain, so please take a look at the photo's.

basically part of the welded head seems to be chipping away, and they
aren't sure if this is a failure or if the little bits should be bent
and broken off prior to install, so they dont come out down the road and
end up inside the motor.

I took a few other shots as well, showing things that cause me a bit of
concern.

any advise, suggestions or other misc tomfoolery is of course welcomed.
