I've always adjusted them this way.Hot.
pop the distrib cap rotate(bump) motor to no. 1 on cap.Set balancer to TDC 0....Adjust both intake and exhaust for no.1 cylinder
Rotate counter clockwise 90 degrees or 270 on balancer and set both for no. 8
Rotate counter clockwise 90 degrees or 180 on balancer and set both for no.4
Rotate counter clockwise 90 degrees or 90 on balancer and set both for no. 3
Rotate counter clockwise 90 degrees or 0 on balancer and set both for no. 6
Rotate counter clockwise 90 degrees or 270 on balancer and set both for no.5
Rotate counter clockwise 90 degrees or 180 on balancer and set both for no. 7
Rotate counter clockwise 90 degrees or 90 on balancer and set both for no. 2
Rotate counter clockwise 90 degrees or 0 on the balancer and your back to no.1 again... :wink:
Button on firewall. and maybe 10 minutes.

In My Few Years,I ALWAYS go .004,Tight Cold IRON Block,Alu.Head.
Now with a ALL ALUMINUM Motor,that is a Shot in the..............Well lets just Say TRIAL and ERROR!?
But,if .006 works for you,than Use it!!!
Even when You set the Lash @ X,it may be DIFFERENT that the Way I FEEL X?
But a Constant Proceedure is a GOOD Rule of Thumb!

Ok, so as a beginner I have to say I feel like Tod said... by the time i get to the other bank, I am loosing temp & I must work fast. Again, from a beginner standpoint, I hate to rush. So- (correct me if I am wrong) there is about a .02 variance from hot/cold right? So if my lash is .26/.26 @ temp, I can safely go .24/.24 cold right??

I adjust mine like Demented explained. Exhaust starts to open, adjust the intake. When the intake starts to close adjust the exhaust. I also adjust them like Tod said, .006 tighter when cold. Works out great for me.
