ProComp/Speedmaster aluminum heads

Is the speedmaster sale usually site wide on everything or just the heads? Even before the sale price, it looks like I can buy bare heads, the ideal springs for the cam I’ll be running, valves AND rocker arms and head studs for less many than the assembled SM heads. I don’t have valve seals or retainers/locks in that price but by buying all my own stuff, I’m currently about $130 cheaper than assembled heads. Now if everything goes on 30% off sale, ding ding!
