In my case - NO. The T.W. installed backwards causes very rapid wear of 
the crank. The material that the T.W. shell is made from appears to be 
very hard steel. That rubbing up against the crank (when you apply the 
clutch) digs into the crank. My washers never fell out, but after about 
10K miles, the T.W. contact surface on the crank was "dished" about .010, 
maybe a bit more. I brought the crank to a crank guy and he said "toss 
it". Seeing that a brand new TR6 crank costs about $179 from the big 
three, I agreed and tossed it. He could have fixed it, it just would have 
cost more than $179. It's the crank - why risk having it fail

But no, my block was not damaged.

My point was, I had minimal end float after the rebuild, .003 as I 
recall, that end float remained at .003 to .005 for over 9000 miles. Then 
I noticed some slop and it wore _very fast_. To around .060. The crank 
never touched the block in my case.
