New Magnum heads for 347 with Flow data

This shows the amount of work just to end up with a closed chambered head that flows like a stock 1.88 360 head.

20 min per port, includes porting and NO valve job im sure. Not 20min per head

this is hillarious.

When you get done working a magnum head to where a mildly '250's cfm' ported La head flows, the port volume will the same..EXCEPT you will have major air speed issues from there out from things like the pinch and roof height . Get the ports big enough to slow things down, if you can without spending way too much time to almost get it and then having them crack on the motor.

what was it you said RAM, theres such thing as too much air speed? lol

And you started out pressing the velocity button and then turn around and tell me there "theres such a thing as too much air speed" back and forth you go.

You didnt respond to my points becaue they are all right on the money.
Ive been doing this for 18yrs, where you been??

Thanks again
