Hello,
My first major work on the car and I'm having trouble identifying the head. I noticed the car had a rebuilt engine since there was a tag saying so on the block. Attached is a few pictures. One of the head and another of the intake manifold. There is a N42 stamp on it but looking at other pictures of an N42 head this one appears to be different. HELP?! I don't want to purchase the wrong headers.
As you can tell this looks way different than the pics on this auction item: http://www.ebay.com/itm/Datsun-Z-240Z-260Z-280Z-ZX-Rebuilt-N42-Cylinder-Head-/400244055278?pt=Motors_Car_Truck_Parts_Accessories&vxp=mtr&hash=item5d30679cee
Last, I included a few pics of some damage to the head I noticed while pulling it off.. How bad of an impact would this have on my car? Would it cause abnormalities? Smoking? Funny, this all started with a head gasket replacement :/
