454 427 Exhaust Intake Valves Springs Big Block Chevy BBC

All the parts you see pictured were removed from a 1969 427. I do not know the brand as I see no numbers or brand name. The pistons,rods and crank were all GM. I did the best I could with measurements but the lengths were hard to get the caliper on straight. But the numbers are very close. All parts look to be good except the exhaust valves have some galding on the stem as can be seen in the last picture. Thanks.
