Is there any evidence of significantly different failure rates between the two styles...assuming the head was in good shape in all instances???

 

I have not had any failures in ones of either type I installed.  I have gotten tractors with head gasket problems of both types

 

I think the big issue is this area of the block decks. Look at the difference with the rest of the surface.

That is weird. 

 

Could be Squonky. I wire brushed the snot out of that area and seemed to look ok. Would stand to reason that's the area that is likely to leak since the hottest.

Highest temps in that area, right?

Not that I have noticed.  Head bolts loosening up guess it doesn't matter what style.

I'm thinking distortion of the deck from the heat cycles. I picked up a small set of precision parallel blocks I'm anxious to try out on my Power King when I take it apart.

Head wasn't bad as some. Did'nt take much glassing.

Just 6" long precision ground straight edges. I can lay it across the deck and lookfora low spot.
