When he corrects the distributor advance curve he will have no lack of low end torque or throttle response.
As long as he did not fubar the cam install its fine as is.
Correcting the engine compression ratio is not that hard on this motor
with the dished pistons. Its not an issue to "driveability" or idleing etc
But will add power by correct ing the true compression ratio.
