Response to Valve lash

...I agree that .022 hot is a good start. Note too when cold (I'm guessing iron heads/block) to add .002 (.024 total) when cold and re-check after warm-up.

Lash on a New Engine Prior to First Fire

If you are lashing a new engine prior to fire up, or setting the valves cold for some other reason, the lash settings need to be TIGHTER than the hot lash. The Exception will be an all iron engines. I recommend setting cold only when you have to. The only proper way to get the exact adjustment is hot as specified. The recommendations below are relatively common. A few thousandths loose probably won’t hurt just to get the engine warm as long as you don’t take it to 10,000rpm:

The Most Common Combinations:

Iron block with Iron Heads: ADD .002” to Lash Settings

Iron Block with Aluminum Heads: Subtract .006” from Lash Settings

Aluminum Block with Aluminum Heads: Subtract .012” from Lash Settings
