CP I feel the pain brother. I bought a set of 34118915 T/A heads for a T/A engine I'm building. Yesterday the machine shop called and told me to stop in after work. Under the exhaust seat we found this crack. I called the guy I bought them from and he isn't being very promt returning my calls. Good parts are as hard to come by as are honest people. They weren't cheap and who knows how it's going to end up. I didn't mean to hijack the thread but maybe we need an area like E-Bay experiences to reward vendors, an flea market sellers with positive comments on our experiences with them.
