I'm pretty sure that when daisy chaining the ohm rating stays the same compared to normally seting up the 2 different cabs directly from the head. So 2 8ohm cabs would always end up being the 4 ohms power rating comming out of the head when daisy chaining and normal setup right?

Yeah, that's right.

Unless you do some custom wiring, no matter whether you daisy-chain or connect directly to the amp, your speaker cabinets will always be connected in parallel. 8 ohms plus 8 ohms will equal a 4 ohm load, 4 ohms plus 4 ohms will equal a 2 ohm load, 8 ohms plus 4 ohms will equal a 2.67 ohm load........if you want to get into 3 or more cabs, you'd best have a clear understanding of how to calculate impedance.

The formula for resistance in a parallel circuit is Rs = 1/(1/R1+1/R2+1/R3+...+1/Rn) where R1, R2, etc. are the ratings of the individual cabs. Rs is the total load.
