I got a nice set of new, takeoff springs and retainers. I took them off new EQ heads and replaced with beehive because I was running a hot Hydraulic roller. Here are the specs. perfect for a hot hydraulic flat tappet cam or mild hydraulic roller and I believe they will fit factory heads with no machining.
