I am only going to post on this once.I offered to help the guy with getting the head repaired.But he must not have a machine shop that is capable of it.I did not know there was anything wrong the heads at all.They had been ran with know problems and were freshly refinished.I didnt have the money to give the guy back because the reason I sold the stuff was to get caught on some bills.I have a wife and 4month old baby and the bills that go along with it.Call me scammer if you like I have been selling on here for 6 years with know issiues until you.That is all and is all I am posting.
