What is the physical size difference between MW ports and standard ones?

I am going to be buying a crossram intake for my NSS car, and am not sure which one to buy. I need to pull my current intake off and see if the ports have been hogged out or not. The guy I bought the car from said the heads were ported, but wasn't sure to what extent.

thanks

Few guys take their ports all the way open to max wedge size. It's a substantial increase in port size and not the right move for everyone.

if they are still stock size I suggest A&A transmission they make a x-ram in both max wedge and non- max port ,not to bad on price also, I myself used the eddy victor max heads and a stage II manifold on my engine with 2 holleys.

Here's a MW gasket on a 906 head. If the top of the port on some factory castings is cut to the gasket size the raised surface gets thin or non-existent.
