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.

I use the EOIC method and set them cold. Trying to do it hot sucks plus by the time you get them all done the temp has changed so how can you be consistant? I set mine .006 tight cold.

HMMM, not one mention, of the "white rabbit, and the bird with a flexible bill," method. :o

I didn't know you were looking for the high performance "white rabbit, and the bird with a flexible bill," method. I didn't know you had a vette engine. :lol:

Tod,
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.

Don't have to feel like that. Be happy you got the correct answer by answering the question incorrectly.
Get it?
