Valve Lash

Valve Lash

Exhaust Open/Intake Closing
When the exhaust valve on the cylinder you are working on begins to open adjust the intake valve
When the intake valve opens all the way and is closing adjust the exhaust

Iron block & Aluminum heads subtract 0.006 when cold My cam calls for 0.016 intake & 0.018 exhaust when hot,but UDHarold said that 0.012--0.014 was fine.This averages out to 0.015.Set valve lash at 0.009
