Quality castings with good machine work. Required disassembly to clean a few bits of aluminium shavings and blasting media stuck under valve seats.On my flow bench using 4.010 bore, radiused intake, and exhaust tubes, they flow roughly 4% less than claimed. However with slight port and bowl cleanup, easily picked up 6% flow with minimal increase in port volume.
