Do not use the stock aluminum rockers. Go with rollers or at least the stamped steel rockers. At high revs the aluminum ones will wear unevenly thereby changing lift ratio on your valves. Mine varied from .010 to .025 per side on each rocker.
Grind off the A.I.R. bump in the exhaust port, block the crossover, replace valves with large SS Ferrea valves and hardened seats. Cheap fixes for stock Olds heads.
