I try not to believe everything I heard about a person or place, but I went to Thrift twice with 2 different cylinder heads for my car just to have them shaved and they told me both weren't no good so I kept going back and forth to Jacksonville junkyard trading the cylinder heads. The second time I went to do a trade, the guy at the junkyard asked me where are the cams. I had no idea Thrift was taking off the cams and keeping them. The guy at the junkyard told me this is the second cylinder head returned and the cams are missing. Anyway, the junkyard traded me another cylinder head in spite of Thrift taking the cams and keeping them. Then come to find out Thrift was tampering with the cylinder heads. There was never anything wrong with either heads until I took them to these people. I wondered why I was never charged for the pressure checks, etc (which I didn't ask for), that's because they were taking parts off the cylinder heads.The first cylinder head, I was told the valve were burnt. The second cylinder head I was told it would not hold liquid. That's because they tampered with them or just being dishonest. I took the cylinder heads there just to be shaved and they so called found all this other stuff supposedly wrong with them. They were doing other work on the heads I didn't ask for which was going to cost more money. I will never use these people ever again. They are very dishonest people.
