hey i baught a head and i was told it was a type r head didnt even think to look at the code but the head says pr3-4 and i thought that was a b16 and a type-r is p73 so what is my head a b16 head or a type -r?
paid 650 for it but its worth the money even if it is a b16 because it has a small pnp and crower stg3 springs and tit retainers but newho what is a pr3-4 head?
