1969 Race Dart w/ 426 Hemi- garaged for 45+ years

For the new valve covers they machine the breather holes. I don't like the breathers they offer and doing research it has the nipple for a hose to a separate tank which I am not going to do. Searching I can't find a lot of options for push-in style breathers that look good. I am thinking something like this.

The breather Ray Barton puts on their covers (no-go for me)

Push-in option I am looking at?
