Aluminum head washers

Another quick questions...

The bike didnt have any of the aluminum washers under the head bolts like it should have. Is there any problem with me just finding a similar size and thickness in stainless or steal?

stock rd ones are steel, the aluminum washers IMHO are too soft to run. i run steel ones, but on the lightweight i have titanium with aluminum head bolts. ;)

FWIW the DG ones are steel too http://www.2strokeworld.net/forum/index.php?topic=55.msg647#msg647

Watercoolers (LC, RZ, TZR, etc) use copper crush washers at the head bolts that are within the water jacket.

Never seen aluminum ones.

rdlc topend studs & bolts don't go into the water jacket.

True. Maybe it's just TZR are like that.
