Its possible your card isnt listed for that block simply because they never actually tried it. If I was in your shoes I would order the block and just test fit it to the card when it shows up, if it fits than you are set, if not than just send it back. As for the temp sensor, its nice to have but certainly not needed, you have built in temp monitoring on your hardware. Generally speaking knowing the coolant temp is a "nice to have" not a requirement.
