It was priced at 32.00 for the level and 14.00 for the seals to be installed. When I went to pick it up the price was 108.00. The guy that had took the head in had put down for it to be pressure checked and a valve job. None of this was asked for but I still had to pay for it. I have been a customer for over 20 years but they have lost a customer. I will never go back for anything. So be very wary and get everything in writing if you choose to use them.
