Default Valve stem seal help

1991 Mazda B2600i
Destroyed 4 new seals on the first valve (easiest to get to)
These are thin copper (?) shells with a spring loaded runbber ring on top.
Can't seem to drive them straight.
I've installed thousands of large seals over the last 60 years, but this has me baffled. Using a socket and tapping gently. Always crooked.
Will a drive tool set really help? Should I machine an exact fitting driving tool?
All advise greatly appreciated. This is a one time repair to replace leaking seals. Don't mind buying a tool set if it really makes a difference and obviates my klutziness.
Thanks

I do not know.

A quick web search shows a head:
http://www.killers4hire.com/files/ma...402000E11.html

with diagram item #3 valve stem seal noted as 'use special
tool #49 T032 302'. Probably simple to fabricate, tool
sells for about $15.

Thanks Amuzi,
"The press on by hand" doesn't seem to work. Will try again. Thanks.
