I just had my 821 heads ported by LME. I can definitely feel a drop in torque at like 3500, but it pulls really hard past 4500.
I think if I were to go back in time, I would have skipped all the N/A mods and just put a 1900 on and been done with it. But I had a bad head gasket, so I wanted my heads to come back "like new".
