If you’ve been trying to adjust your valves using the stock rocker nuts stop doing that, they were never intended to be used that way. Torque them down and you’re good.
Putting a non-factory cam in your 326 HO is like opening a can of worms. The press-in studs are problematic when used with cams other than stock. The factory rocker nuts add support at the weakest part of the bottleneck stud.
Seriously consider a factory grind like the 066 or perhaps the 068, it will make for a simpler and less expensive installation and save you some headaches.

Fair points. IIRC, the 066 is what the 326HO came with from the factory. No need to mess with anything else provided it's still stock.
