I have the L99 water pump on a 4.8 that I'm building right now. I measured it and a spare truck pump that I have and verified for sure that there is 1/4" difference in "height". The shaft of the L99 pump protrudes through the middle of the pulley about 1/8" so you could grind that off to get the last possible bit of clearance. But, keep in mind that the water outlet on the L99 pump points straight forward and is sticks out about the same distance as the pump shaft. The radiator hose is going to be furthest thing from the block. In other words, if whatever you're trying to create clearance for is also in the way of the water pump outlet, the L99 may still give you some fitment problems with the hose outlet.
My comment about the tensioner really wasn't in regards to the DD A/C mount. I just meant that the L99 pump doesn't come with a tensioner and the LS1 corvette tensioner will fit it (and the 'vette tensioner is about $40 cheaper). I have no experience with the DD mount.
