magnum head porting / pushrod pinch area / etc

I have a set of Magnums, off my "need to be rebuilt" 5.2 that I am going to put on my new "used" 360.

I am also removing the center divider in the kegger manifold, and porting the runners to match gaskets.

My question is on the heads. Supposedly Magnum heads outflow traditional LA heads, but I can scarcely see how. The intake runner is as wide as my thumb, and I do not have Megan Fox's thumb.

• How much material is there in the pushrod pinch area for porting?
• Does anyone have any pictures of home ported heads
• how much benefit (HP and TQ) do basic ported heads offer?

My plans are to gasket match the kegger and heads to intake gasket, streamline the pushrod pinch area, basics bowl blend up to the valve seat, smooth out the valve guide, and open up the exhaust ports ALMOST to the gasket, while leaving a small ridge to minimize reversion.

I am pulling the heads apart tonight, to get started. This will not be an aggressive port, but rather remove obvious obstructions, and streamline the airflow path.

Thoughts?
