The aforementioned 624 heads are most definitely not the 292 "Turbo" head.
Currently, Those 624 heads are being used on the 260hp GM crate engines.
They come with 1.94"/1.50" valves, flame hardened exhaust seats, 1.250" springs that accept up to about .450" lift (If I remember correctly) & 76cc chambers.
