the striker is hardened steel. i personally doubt the effectiveness of cupping its face.

if you have a rocket valve, you wouldn't need a hole at the bottom at all.

when i installed my rocket valve, i also threaded the exhaust to plug it with a grub screw, in order for it to be removable in the future just in case. you can try that route.
