Is a charged headbutt an amplified attack?

[withheldforprivacy]

Like Namu's Buddah attack? Think of it...
-A crippled Goku's headbutt defeated a still standing and fighting Piccolo.
-Gohan's headbutt severely wounded Raditz, at about equal PLs.

Well naturally if you apply more energy into something it will hit harder.
Like a soft slap. And the hardest slap you've got.
If you somehow apply Ki to it I guess there's a possibility.
Do you think Goku amplified his finger when he applied Ki to it? (Against trunks).
