Is there a difference in metal used for the type r dual valve springs and retainers?
and are the type r valves shaped differently or made from a different metal?
and i also understand that the type r has dual valve springs for intake and exhaust, so would there be a difference if i took the smaller intake valve springs from another head and put them inside the exhuast valve springs to make dual valve springs for intake and exhaust?
and links to info would help
