Big Block ticking? Flat tappet cam. Normal?

Later on I will put studs in and possibly helicoil inserts.

@George Jets i will adjust the valves at the same time as installing studs. Probably a couple weeks out.

After fixing that hold down, the tick that was loudest at cylinder 5 went away and it is now equal everywhere on the valve covers when using the stethoscope. Tomorrow I will measure the valves when the motor is completely cooled and compare. Depending on what I find when cool, I may adjust before getting studs.
