Used set of ported irons with T&D rockers for sale. I originally purchased these here: Heads. Per the link they are supposed to be early Champion irons but have no markings that I am familiar with, maybe someone here recognizes the stampings on these. After I bought these they were switched over to the beehive style springs with titanium retainers and locks, 1.55 ratio rockers. I would recommend having them looked over just to verify everything is good to go as they are "as taken off" my motor other than being cleaned up a little. Ran low 10s in the 1/4 with these as they are, under 30 psi. $1000 plus shipping?
