Adjust valves

I do the procedure detailed above......set the exhaust as the intake starts to open and the exhaust as the intake sets on the seat.
Doing it cold , you want to compensate for expansion when the engine is at operating temp.
O.K. , true confession time.
I had to edit because my memory failed me..........I went .015 tighter with aluminum heads to get the number I wanted , not what they recommended.
card calls for .026 , I wanted .018
.011 cold got me .018 hot. , so there is a .007 difference in my case.
Then I read some guys who say with iron head and block .001 to .002 tighter than spec. when cold will give you your number when hot.
And some who say that you can set the lash to the spec and it will not change when hot. I am dubious , but as they say , your mileage may vary.
I'd squeeze them a couple thou cold , and check them hot to see where it leaves you.
