I've read several post saying that porting the lower cobra intake is worth some good horsepower.
If I do this, will I have to port the heads as well (GT-40 heads) and port match the upper. In my experience, one thing generally leads to doing a bunch of other things and spending lots of unexpected money! Just trying to keep it under control here.
Edit: after christmas I will be changing my head gaskets and advancing my cam, so I figured that if I am going to port the lower, might is well do it now.
