Just after your opinions on what stacks you use and if anyone has got info on which stacks are best for a Genll for 1- torque and 2- HP.

I've read some threads but want some deeper info than they offer-personal preference/written info if poss.

Cheers.

Dont get too caught up with the cnc part. CNC only ensures repeatability, not quality. The ports are ported by hand then digitised to create the cutter paths. If the initial porting that was digitised was crap, then the cnc machined ports will also be crap.
