Hello,
Just curious what procedure fellow Mopar enthusiasts with mechanical cams use to set valve lash.
1) The last time I set valve lash on my Barracuda, I followed Hughes Engines' procedure:

The EOIC procedure has you set the lash on the intake valve when the exhaust valve for the same cylinder begins to open (EO). The EOIC procedure has you set the lash on the exhaust valve when the intake valve for the same cylinder begins to close (IC). This is Comp Cams preferred method, as documented by their youTube video:

Finally, I read this Drag Magazine article on setting valve lash:
http://www.dragzine.com/news/how-to-set-and-adjust-valve-lash-like-a-pro/Near the end of the article the top engine builders provide their 7 tips for setting valve lash. I didn't understand tip 3 ("ignore chilton manual procedure") when the engine builders said to set lash in firing-order order. Is that the Hughes Engines procedure (1) or is that setting both intake and exhaust on the cylinder that is about to fire procedure (3)? The main thing I want to ensure is that the lifter is truly on the base circle of the camshaft when I set the lash. I fear using procedure (3) might result in setting lash on the intake or exhaust when the lifter is NOT on the base circle.
How do you set valve lash?
