Does anyone know the code on a b20 head and a b18a head?
there is a code on the side of the head that starts with a P and then 2 numbers following? I was wondering if anyone knew what the numbers are for both heads?
P75 is correct.
Watch out for automatic P75 heads, as they contain auto cams which make less power than the 5 speed variants.
