Just getting my L92 nitrous motor installed I have a questions about plugs for these heads.

Do I need a taper seat plug or a gasket seal plug. Plan to use either a B8EFS Taper seal or a 5671A-9 gasket seat plug. Which is recommended?

Thanks in advance for your input.

they both work.
Ive used TR-6's (taperd seat) and -9/-10/-11's with the gasket.

There is an NGK B9EFS that is tapered seat. Anything colder and you will need to go to the 5671A-X. Let me know if you have any other questions.
