455 G head valves

Hello everyone. I have a '79 Trans Am that has had the 403 replaced with a '74 455. I am getting a nice set of G heads ready for when I freshen up the motor, replacing the J heads. G heads are from '71, and I am having a difficult time finding correct valves, unless I want to go with Manley Severe Duty at $40 each. My exhaust valves are 1.625, with 45 degree angle, and intakes are 2.075 with 30 degree angle. The only matched sets I have found are from Qualcast, and I know nothing about them. Ferrea makes intakes, but not exhaust. Any ideas? Thanks!

Typo! V1172 should be V1772!
