I have an older FSA SLK crank (5+ years old ?) After I remove the 7mm bolt, ther are large threads inside the crankarm, plus the threads that the bolt was using. What tool do I need to pull the cranks off ? Ultimately I want to pour something down the inside of the seat tube to free a stuck carbon seatpost in my CAAD 8 frame.

Yes, but hoping for a more specific description or model. I have mostly "old school" tools.

You might need the correct self-extracting crank bolt which came with the crankset (it's available as a spare too). Or you might just need to re-install it and the cover using a pin spanner (is your "bolt" actually a bolt plus a washer with external threads?)
A standard crank extractor probably won't work because of its pusher's small size which will run inside or try to strip the spindle threads. Standard crank extractors sometimes didn't work for ISIS cranks taking M14/M15 bolts and the same is likely with the bigger ISIS/Octalink puller paired with the even larger M17 threads on the Mega-Exo cranks.
For instance the Park CWP-7 "universal" puller has 11.3 and 16.3mm pushers.

Usually the left arm just falls off.
