Big Block ticking? Flat tappet cam. Normal?

I’d set the lash at like .012-.014 cold(sitting at least over night).

Put 100 or so miles on it, check it again cold(sitting over night).

You want to see that it’s still where you set it.

I did set it at .011 and .013 cold when I put the studs on and adjusted the valves. I will put some miles on it and post what I find. From when I installed the 1.6 rockers (440 source brand like the 1.5 ratio they replaced). The lash opened up .003-.004 on both the intake and exhaust. I am not sure if that is normal break in or uniform wear.

And I have put on 100-150 miles since the original 1.6 install and a few full throttle runs up to 100 mph.
