I not going to use these now so have to let them go to a good home. They were modded by very well known racing shop DPR Racing to make big power. It was not cheap and take 2 months to get them back, but no time to have them installed. Had them do Stage IV on these, and you can see on their website the cost and what was included: http://www.dprracing.com/snissan.htm
They polish the exhaust side and make it match the stock manifolds or headers. On the intake side they did special work to improve air going to cylinders and provide more flow. They also did polished inside the chamber for less chance of detonation so I can run more timing. They are supposed to be good for 30+hp from what they have experienced.

Here are some pics of the work. Just need to put in parts from stock heads and they ready to use.






Only asking $400 plus shipping. I don't know how much shipping will be, because they weight about 50 pounds.

 

All pm's respond. Thanks for the interest, but still no firm buyer.
