Nothing mate, just offered a pair of head's for sale to guy in u.s. and when i checked them noticed one still had the t/b rubber on and it is a tls one ,not tlr.jagboy1 said:there is a difference dude.i think the 98 S onwards are the same as R heads. 97 S's have different shape porting on the inlets.... they all fit though.
what you broke????
