New valves cutting or lapping?
 

hi,

i just got a set of new supertech valves for my d16, the head is in exelent shape,

is it nessacery to cut the valve seats or lapping will be enough?

I'd do a valve job. Mind as well.

Otherwise check the new valves in the head with die makers bluing ink. It might be sealing fine without the lapping.
