X-Head Porting....

Lookin good! @MOPAROFFICIAL told me about a "%" that the throat vs valve seat diameterbshould be, I cant remember the # is exactly, something like 90%?

It is 90%
However, with the stockish low lift cam that these head would be going on........The throat should be a little smaller then that, to keep the Velocity Up..........
Just the way i look at this.

Ok.. I dont know what the throat is... so I can't measure or calculate it.

I'm assuming it is the "primary choke point?"
