Over at Gils Garage, they speak highly of the quality and volume of water the Mr. Gasket 4367 thermostat  provides for Y blocks. Best price I have found is $16 and change with free shipping on Amazon with orders over $35. They average $20 or more at all the other places I looked. Is anyone familiar with this thermostat for the Y block and is there a general consensus that its that much better than a standard issue?
