The type of compressor in post 2 does not compress the inner spring.
You will not enjoy it....... especially if it has fairly stout springs.
The type Comp sells with the dummy shaft is what you want.
As for whether you break the cam in with the inners removed or not...... I tell my customers....... if you try it without removing the inners...... and it eats the cam...... it’s just shame on you.
