Its the second cam i speced above. 212/218 .522/.529 114lsa and while im gonna be in the motor ill pull the heads swap out springs to ls6 and port amd polish the runners and mill them just a tad to raise compression to 10.5 +/- how much would it take as far as milling the heads to raise compression from 9.4:1 to 10.5? Anybody have any input?
Totally depends on your setup.. rod length, displacement, combustion chamber CCs...

As for changing the springs, I just got into this debate in another thread, there is nothing stopping you from changing the springs with the heads on the block. And there are plenty of stalls out there that are fine for towing, as long as you have a good cooler.
