Hi List, I'm selling a bare rwd SR20DET cylinder head off a '91 Nissan Silvia S13. Not cracked nor warped. Perfect core for a project or to send out for a port/polish job. springs, retainers, valve, cams are all available too. make me an offer for just the head or the head and valvetrain. I want to clear up my garage. Thanks, Eddie sr20roadster@yahoo.com Bay Area, CA
