Are the gaskets and seals in this kit any good?

I have already done my research of what i want to get for my engine rebuild, but when i saw this kit I saw that it comes with most of the gaskets and seals that I would rather not hunt down individually if i have to. My question is, has anyone used this kit for an extended period of time and had good results. I dont really want a blown head gasket or an oily driveway. I am not expecting much but if for some stroke of luck these included parts are actually good quality I wouldnt mind saving some time and money. Here is the link for what i am asking about http://www.ebay.com/itm/NIPPON-RACING-JDM-CIVIC-TYPE-R-PISTONS-BEARINGS-RACE-ENGINE-CONVERSION-KIT-/180816666352?hash=item2a19835ef0&item=180816666352&pt=Motors_Car_Truck_Parts_Accessories&vxp=mtr

Some of those parts say Made in Japan so it could be some good stuff. I wouldn’t know though. Probably aftermarket Japanese parts which should be good. I’d also like to hear if anyone has used this and if it’s quality.

I dont think I am going to mess around with the bearings, I will keep them honda colored ones so i can get the correct clearances. I hear good things about people running the nippon racing pistons but never about the rest of the kit.
