I know that 7454 was good when I had it on an X15 before it left Ashington.
7455 is a dog compared to 7456 now - 7456 is just above the performance of a Gemini on the X12 while 7455 is just underpowered. However, given Durham did wonders with 7432-5, shouldn't be beyond their power to get 7453-6 back to decent standards.
