Your absolutely right, I did have a cracked block but managed to fix it. The head and manifold sadly are beyond repair. I am located in Calgary, Alberta, Canada. I do have a friend in Montana that would be a somewhat reasonable location to have U.S. parts shipped to. I did see the posting of the complete motor, but seller says he has not herd it run. I actually contacted him and he would prefer to sell as a complete. this would make things too expensive to ship. I guess I'm still searching, thanks very much for your feedback,much appreciated.
Regards
