Hello all,

Up for sale is a new (with box) NSX front cylinder head, including A/T-spec springs and valves. I believe it was produced in Oct. 1999 according to the date stamping.

EDIT: This is an 3.0L spec head with 35mm intake valves, would require modification for the 36mm intake valves on a 3.2L engine. It also has secondary air injection holes on the exhaust side that can be blocked off for use in pre-'00 cars. Thanks MM below for clarifying

In summary, included is everything in the pictures below:
-Bare NSX front cylinder head
-Cam caps & holders & hardware
-A/T-spec valve & spring sets

Not included:
-Rocker shafts or arms
-LMAs

Asking $1,200 plus shipping, open to offers. The cheapest you could get this combo new from Honda looks to be about $1,750 for the bare head and $550 for the valve set, or $2,300 + shipping total from overseas.

Edit: Reduced price again. I'll be moving states in Sept. so time to ship might be limited.

FYI based on Amayama that part number is a 3.0L head meant for year 2000-2005 emissions systems, it should work for older vehicles but will need the air injection holes above the exhaust ports blocked off depending on the year. Intake valve size was 35mm for all 3.0L engines and 36mm for all 3.2L engines so to use 36mm valves in this head you'd need to have the seats cut and throats bored/blended accordingly.
