a dealer told me that the head gasket was bad on my kohler and he said 200 to replace both. i called 4 dealers. $200.00, 2, 450.00 3, 1 hour $52.00 plus gaskets. and 4th dealer said 2 hours at $54.00 plus gaskets. my question is who do you think i should trust and go to??? the 1 hour guy said he dont think it would take any longer than that and i just want to make sure he is right. anyone ever do them and how long did it take??? thanks for any help..
