455 heads on a 403

[Fire eagle]

Has anyone done this swap?

I have been told that 455 heads will bring a 403 to life.

Looking for opinions.

While my 403 is on the engine stand would like to beef it up before installing in the car.

@Fire eagle the problem won't be the head but the intake.

The 455 heads have a taller intake profile so your 403 intake won't match up.
