I soaked my lifters in oil. Coated the bottoms with assembly lube and installed them. With the intake off, I set my pushrods at zero lash plus 1/2 turn while the lifter was on the cam base circle. Tell me if you think I missed something important.
This guy has a very interesting method which I might have followed if I had not already soaked my lifters in oil. He installs the lifters WITHOUT SOAKING them in oil first. He then tightens each rocker until he has zero lash, rotates the crank 90*, tightens loose pushrods to zero lash, rotates another 90*, keeps checking rod lash until he has all pushrods at zero lash no matter where the crank or cam is. He then gives each rocker a 3/4 turn preload. Then he adds oil to the engine and primes the oil passages and lifters. Done.
Being a novice, I might not see problems with his method.
Flat tappet adjustment method.
