Here is the situation... I have scoured the net and came up short. I am in the process of having my '86 Z24 from my 720 being built... the wall I ran into is I need intake vavles, exhaust vavles, springs and retainers. I don't want to buy stock parts... but I can't find aftermarket stuff. Main question is, do the KA24 parts fit these locations on the Z24? If so, I have plans to get them, but don't want to make a huge mistake wasting the money if they don't. I would like to do more research myself, but I'm currently deployed to Afghanistan, so I really need the help. Anyone know anything? Thanks
