I went ahead and ordered a complete Comp Cams xe284h (.507/.510 lift) kit. comes with cam, lifters, timing chain, valve springs, retainers, locks, and seals.
i called up my machine shop and they said itd be about $130 to enlarge the spring seats and add screw in studs and guideplates and put the heads back together.
thanks for the input, guys.
