A set of six high quality made in the USA valve seat inserts 44mm
These were originally available from Nissan Motorsports . They will be useful to upgrade a L6 head that still runs the softer bronze seats. All 240Z heads and some 260Z I believe.
They will also facilitate using a larger 44mm inlet valve (std L28 size) in place of the 42mm 240Z size.
New old stock
SOLD
PS I probably have some used 44mm inlet valves(used) available if you want some.
