Having removed the engine last week, I am starting to put it all back together again and one of the issues is the exhuast headers.

I need to replace the gaskets on them, but it would appear that I can get either copper washers or aluminium fibre washers for the headers - same price for each - so what is the difference and why would you by one over the other?

Cheers
Craig

i think i have a set from the R1 (copper) in the garage they might be the right size you can have them if they are any good to you

John, that is very kind, but to be honest I was just trying to understand what the differences were in the two options. Is one better sealing, is one more re-usable, sloppy second choice etc etc.

Cheers
