These are from an SR20DET that was supposed to have Tomei stuff in it, but they are not Tomei, I believe they are REV which was an ok company, but they just were definitely used and worked great considering the head had 270 Camshafts and did not bind, so if you are looking to run really large lift in cams you need better springs and high RPM Dual springs are the best way to go. The retainers have a little scratching on them from install and removal, but nothing that affects the integrity or strength of the Titanium piece. These are priced to move, tired of looking at this junk head that I got screwed over on it pretty bad.
$100 shipped for a complete dual valve spring and Titanium retainer setup, comes with the items you see in the picture. I bought a Supertech retainer to compare installed height and see if it fits just like these and the installed height for the shim and valve were identical, so these are for an SR20 valve train for sure.
The valves are not for sale, they were not meant for an SR20 and are junk, but if you want them, I'll throw them in with the springs for free otherwise I'll have my buddy make me a tie rack or something with them. I don't sell useless parts ever.
