I don't mean to be dumb but I'm not sure what I'm looking for in that picture.
See the part of the cylinder where it gets bolted to the case, right next to the intake area? It is beefed up around the ears. The stock ears sometimes crack or even break off.
ball park what does this cost to have done---don't you typically have to bore the cylinder once over after welding it up.
Price will depend on who does it. And yes, the cylinder will need to be re-bored as well as decked.
