Wail away with a 5lb several times to make the marks big.....really big.

I said "Why did you stop ? A few more whacks, and you wouldn't
need the drill press".....
That's so the hole would be countersunk already when the hole is drilled.

I don't mind wood or plastic. Messy, but it don't damage the ways.

Nice punches!
Just don't use sodium filled valves I'm sure you are aware of what can happen...

If not check out 1:45 to 1:60 of this video
https://www.bing.com/videos/search?q...EF10&FORM=VIRE

just a heads up for those who don't know if ya have one made into a punch or cutting on a band saw with cooling fluid or some how crack fractures while punching and moisture or water is introduced unknowingly could be disastrous

Heat dissipation. Keeps the vales from getting too hot.

yep helps keep them cooler and can be found in all types of automotive and diesel heads used usually in the exhaust valve but in some applications you can find them in both intake and exhaust.

I keep an assortment of valves around to use as light duty seal drivers. Never thought about using them for center punches.
