i got these brand new a while back, they are the ones from vincihighperformance.com that sell for $200 made by RPC...they say the will seal and will not leak like the ones off ebay for $100. these are still new in the box, never installed, i have the bolts and the new gaskets, as well as 2pcv valves i was going to use with them, i will let them go for $150 shipped inside the USA.
