The 7/8 master and 3/4 slave (which is what the Howe #829 is) should be perfect for you and your slave also has 1-3/8" of travel. I have the same set-up on mine (although Wilwood brand master and slave) The only issue you may have is that often the dirt track parts manufacturers (like Howe) won't warranty their cylinders on street cars because the duty-cycle is a lot different. You may very well be fine as many other guys have done the same as you. Best of luck on the bleeding process.
