My grandfather, CJ, asked me to post these heads here for him. If anyone is interested please message me and I can provide his contact info to you. I can answer questions as well about these heads. Have a nice matched set of 62 409/409hp 690 heads. These are the heads you need for correctly building a 62 409hp dual quad 409 or a 63-65 425hp motor. They have the larger valves and extra intake bolt holes. These heads have matching date codes of 1962. Heads have been taken apart, hot tanked and then magnafluxed. The rocker studs are the original studs with the factory set pins in them. The heads have not been rebuilt, that is up to new owner depending on what specs they desire for their engine. Asking $2300 OBO for these heads.
