O.k. I am aware that most machine shops today are no longer familiar with flathead engines. So what do I tell them to be sure and check for and or install properly, that isn't common to other engines? I am terrified of spending alot of money on a rebuild only to have some thing go wrong internally shortly after putting it back in the car. I have heard alot of horror stories out there about rebuilds on these flatheads that went awry. In fact thats what happened on my parts car. The guy that owned it prior to me said something went wrong with the rebuild, he took it back and got in a fight with the shop shortly after, and went down picked it up, partially torn down. Thats when he sold it to me as a parts car. Depressing and scary, I definitely don't want to run into the same issue. Any advice is much appreciated. Thanks, Richard
