how do i adjust valve lash?

Answer 1

depends on the particular vehicle.

Answer 2

Your E-mail address it too new and unverified. I have been trying to get back to you for a couple of hours.
In response to your e-mail question,
Yes.
Haynes, Childre's and Climber's (I know -- spelling; intentional;>) ) offer very little in the way of real support.
That is why I recommended that you go to the library. There you should find a SHOP manual, not just a repair manual.
The official General Motors manuals offer ALL the information for the vehicle, not just the most popular.
Please don't be offended by my tone. This advise is the same I have been directing my apprentices to follow for nearly 40 years. It really does work.
The HARD part is the discipline required to slow down and read, instead of HURRY UP and finish.
There is an adage we use, sometimes with a sharp tongue: "If you can't take the time to do it right the first time, where are you going to find the time to do it right the second time!"

Good luck. Hope you get it going with very little more trouble, and that you do indeed have the correct head!!

The lifter pushes up on the push rod, the push rod pushes on the rocker, and the rocker pushes the valve open.

When you replaced the gasket, it was thicker than the original, and therefor creates a larger gap between .........
