I rate 2 stars because I'm missing a inner spring and didn't realize until I started installing. It suck because now I have to wait and possibly uninstall to ship back.. I contacted them and no response yet but it hasn't been 24hrs. Shipping was fast and kit seemed to be nice and packaged well. Will update when my issue is resolved.UPDATE! Their reponse was great they resolved my issue no hassle. Thanks! 5star! Now I can complete my build (Ls 6.0) 243 heads and SS3 cam

Used for cam swap , titanium for hi heat . Easy to install with the right tool. One of the seats was a .005 too small has to get a socket to seat it on the head . Other than that great quality . Extra retainers included . Used on ls3 Camaro ss 2013

This is a bargin for such a complete kit. You get everything you need in one box including springs, retainers, locators, valve stem seals and keepers. The kit arrived days ahead of scheduled delivery and was well packaged and well made. Btr springs have one of the best reliability records in the business. Great deal, fast arrival and great product. Thank you michigan motorsports and BTR!
