Sounds to me that the timing is not being advanced correctly when under load.

Suggest to the shop that is working on it to check the timing advance under load. The shop should know how to do this. It's very simple to do.

Check your advance in the dizzy. It might be stuck or has incorrect springs installed on the weights.

Check to be sure that the cam timing gear is not cracked and flexing under load.
