Or can these be machined and repaired?

They are off of a '73 Bonnie with 8k miles. Unfortunately the top end was removed long ago, and the cylinders sustained the storage damage. The rest of the motor is in good shape, except for whatever reason the top was removed to begin with. That's why I'm splitting the cases for full rebuild. Everything else looks almost new, tho.

I'm trying to post a link to the pics on my Flickr so you can see them. Below may only be one pic, but the rest should be there on the Flickr.

Thanks for looking. https://flic.kr/p/6617743111

Thanks for the quick reply. What do you think about the broken cooling fins? Can they be heli-arced back on? After boring them over, and the possible reattachment of fins, do you think I'll be near or over the $400+ for a brand new set?

And yes, they are standard bore.

Thanks!
