Default Precisely what WILL the L92 heads fit? And LS7 heads fit?

We need one post that precisely sums up exactly what each of the L92 and LS7 heads will, and will not fit on. I see a million posts, each asking for confirmation to their specific application: "will the L92 fit my Lq4?" , "will the LS7 fit my resleeved LS1?", "will the L92 head fit my stock bore LS2?", etc, etc. A million combos out there, so we need to know the bare minimum bore size for each head AND we need to know the piston valve relief angle/design requirements to accommodate the valves of each head. So will someone chime in and sum it all up nicely. Thanks!!

No, L92 and LS7 are not cathedral ports. They need their own specific manifolds.
