I’ve seen a lot of people use lifting plates on intakes.
I don’t trust them, I always bolt the lifting device to the heads, front one side and rear of the other.
Too much at risk for me.
I hear 'ya. I've used the lifting plate on a small block with aluminum heads & AG intake. The 440 is heavier though. The Trickflow heads I have do not have holes in the back side of the head, so can't do that.
