I got a set last Sat delivered from a Company/guy from Houston. They are new with valves, springs and retainers you likely won't need. He told me he had 3 more sets but his ad isn't on Facebook Marketplace now but try him anyway. Valente Cantu at
vcparts.equipment@gmail.com. $850 plus shipping for the pair. I can check on the 369BD in the AM. Know it was 369 and I did measure the valves and they are correct.
