With the right connecting rods (BDD length) and pistons you don't need to deck the block at all. Of course that means other issues with bonnet and exhaust system clearance, etc.
Russ,
The 711M block needs to be decked about 5mm and rebored to suit the Twin Cam pistons for use with the 711M crank and conrods.

I fix the engine mount directly to the engine and use a plate spacer on the other side of the mount to the chassis. My last two engines have been 681M blocks which is where I did the modification originally to get the mount away from the hot #2 header pipe as I'd had a couple of mount failures due to the heat.
The 711M & 701M blocks have the mount base 1/2" thicker than the 681M block so I need to know if it's OK to remove 1/2" and retain sufficient thread length. Maybe I'll need to drill and tap the holes deeper, or maybe make a shorter plate spacer -- there's plenty of time for me to make up my mind on which action to take.
As you can see, there's no bounds to my playing with my favourite toy.
