I don't think the knurled TD glowhead is any different than the regular one.

As to the crankcase...... Just lap (sand) the case on on a flat surface preferably a piece of sheet glass and the burr should all but dissapear. Use very fine grit wet dry paper.

I use 800 or 1000 grit for that operation.

I would go 800 or more like Rusty suggested.

Take a look at the combustion chamber and compare it with a regular head. You'll see what I mean.

This is what your head looks like, right? The knurling only indicates early production.
