Not Ranked
I always set by firing order. On a race motor where I expect to be doing all the maintanance on in the future I set the clearances hot once [ This is usually done on a test stand- If I have to do this in the car I run thru the first 4 cyls of the firing order then restart to run up temp before setting the remaining 4cyls] Then when the engine has cooled down overnight I check and note the cold clearance. This is the setting I use from then onwards so that valve lash can be done in a relaxed fashion knowing that any variations in settings means a problem somewhere without all the what-if scenario's.
