Alright bringing this back from the dead.
So after saying I didn't want to spend $1k on heads. I am well on my way. Someone is selling new l29's on ebay so I bought a pair for $850. they are the factory 19256827 ( i guess 19256821 casting #) heads off of the 8.0 crate engine. Not sure if they are take offs or what. But they come with springs but no rockers. I think they are just normal l29's and need the conversion studs but the literature says the heads are normally fully adjustable valvetrain so not sure if the rocker studs are a different size. Will test when I get them.
So looking now at pistons and cams and deciding if I want to do a roller or stick with hydraulic.
I sent an email to comp and they suggested the 11-408-8
