Hello folks, I have some almost new polished fabricated aluminum valve covers to fit small block chevy. I got these to go on my 67' Biscayne but they won't clear my Ram Horns Manifolds that I put on. They are in excellent shape, a small scratch on the top of one valve cover but hardly noticeable. These retail for $150 new so I'm asking for $100 obo for both. They are baffled to run PCV and/or breathers and have billet rails to ensure an excellent seal against the head.
