I did speak to Pete about this, he is doing my porting....
If I choose to use them again they will probably need to be opened up a bit but they are pretty thick...
Don't know which tool I can use to have it perfectly done...I hear they keep some of the heat away from the plenum but it's not necessary to use them..
