Breaking in my new 383 probably has about 26 miles or so on it now I’ve noticed a slight ticking noise in valve train on number 8 exhaust so I lashed it and it read 17-18 I set the at 15 cold lunati recommends 16 hot . So I ended up relashing it at what I had before . Fired it up no noise at idle just 1500 2000 rpm it not a horrible loud ticking but can here it in car through rpm I put a stephascope on it and listined in the lifter valley and up in valve cover noting super noticeable hearing down there or in Valve cover. They are crower lifters also. Anyone know what could be going on here hoping not bad lift already on a brand new build

Usually lifter failure is a lot worse than .001-.002" in lash. And there would be metal in the oil.

Yeah just found some rockers are touching springs so that could be my ticking and and all 16 valves were holding their lash so could be problem solved not sure yet we will see

If recommended lash is .016 hot and you're running aluminum heads on an iron block, you may be loose hot if you adjusted them at .015 cold. On my stuff, I generally see .004-.006 difference between cold and hot depending on the recommended lash. With a solid roller you are better off being a little tight than loose.

Well, not exactly problem solved. You will be modifying those rockers for clearance as needed.
