"staking" is an old brit term like "spanner".

that means sliding the part into the hole and peening the metal at the edge slightly to clamp it securely.

i usually make 3 or four punches around the port. if it's worn slightly loose i have a dood trick for tightening then up. it's called hand swaging. an old blacksmith term.

use am old long bolt with the threads cut off for your swage. you're using it almost like a punch but you want to shape the end to a snooth, slightly rounded on the edges punch that you can use to tap the edges of the hole tighter with the exhaust adapter in the hole.

give it a little angle so you can work around the stuff in the way.

check the size of the adapter, if its the right size you're in luck.

actually that looks like it is a "reducer'" type of adapter. you can just find or make a piece of straight tubing that won't constrict your port flow so much.

this would be a good time to find out what internal diameters are available in triumph pipes. an exhust shop can open them up slightly if they're a little small.

they can also make your adapters for you . fit em to the pipes before you stake em and trim them so your pipes fit flush.

i think you might want to mark your pipes for flush to the head with masking tape so you can trim em perfectly before you remove them.

go for it, and good luck. this is what rodding is all about.
