super chargers work well,turbos also work well

rather than ask miscellaneous questions and getting random answers:
tell us the application for the engine and what you would like for performance.
biggest obstacle is always budget.

In my opinion, your plans are flawed. You're thinking that you will gain some power by camming up the motor and using those low-rpm heads. Ain't gonna happen. You'll end up ruining a perfectly tractable motor. If you want more juice, pop for a 350 to begin with. I realize you're in Holland, but there must be some 350 cores there.....somewhere.

The swirl port heads were meant to make good power down low in the rpm range with a stock cam and I just don't see spending your money effectively with them as a base to begin with trying to make more power.

If you're gonna be hard-headed and stick with the 305, then at least purchase some decent heads for it....

Any camshaft that you bolt into the motor will have an operating range of ~3,500 rpm's. It will allow the motor to make power from idle to 4,000 or from 2,000 to 5,500 or from 3,500 to 7,000 or whatever rpm range you wish to use. AGAIN, the heads you have are optimized for low-rpm operation and will not be compatible with a camshaft that wants to operate at a higher rpm range. I continually harp on "combination", "combination", "combination because you must use parts that complement each other. If you use a longer cam with those fosdick heads, you will kill off bottom end power by virtue of more cam timing. Any power that you may make on the top end as a result of more cam timing will be killed by the heads. There's no free lunch.

Generally speaking, most builds such as what you're contemplating will benefit from using THE VERY FIRST OFFERING ON THE LIST from the cam grinder, particularly with heads that are designed for low-rpm operation. COMBINATION, COMBINATION, COMBINATION.

Here's the Crane cam....
Crane PowerMax Cam and Lifter Kits 114102 - SummitRacing.com
Here's the Edelbrock I might use....
Edelbrock Performer-Plus Cam and Lifter Kits 3702 - SummitRacing.com
I like the Crane cam because of the 104 degree lobe separation angle, contributing to low end torque. The Edelbrock cam uses 112 and I don't care for that. It favors higher rpm's, something you will not see with your heads.

I might also use this cam....again,....104 degree lobe separation angle and a little more lift than the 114102 cam.
http://www.summitracing.com/parts/crn-114112

Here's Crane's description of the 114112 cam.....
Great for 305 and 350 engines in cars, light and intermediate trucks with optional gearing (or shorter tires). Good low and midrange torque and HP.
Grind number 2020
Oprating range 800-4400 rpm's
Part number 114112
Use lifters 99277-16.... Use springs 99848-16
Duration @0.050" tappet lift 194/204 254 104 (7) 21 .000 .401
Duration @advertised 254 / 264
Lobe separation angle 104 degrees
Intake open/close (7) / 21
Exhaust open/close 26 / (2)
Valve lift 0.401" / 0.423"

Read through this tutorial several times to make sure you understand the precautions of using a flat tappet cam.....
