If the crack you refer to is a normal one that occurs around the valve seat,
it is probably not cause of low compression. You should have a leak down
test performed to determine source of leakge before dissasembling engine. I
would be careful about blasting GEX or any other vendor unless I was
"Absolutey" sure they did wrong. I would not want to be defending myself for
slander. Many things can and do happen to rebuilt engines. Especialy air
cooled. Many low compression problems are caused by the heads not sealing to
the cylinders. Worn and warped cases will cause the cylinders to not sit
perfectly parelell. This will cause these failures and most people don't
think to check this.
