I believe these are Eldebrock valve springs. They were supposably taken off a set Eldebrock heads and replaced with something else. Look like new. They measure 1.400 outside, 1.025 inside, 2.5 high, .180-.185 wire. They come with retainers and 3/8", 2 and 4 groove locks. $60 shipped in the US only. Start a Conversation with any questions.
