Re: Anyone have experience with head porting?
I've done some preliminary testing (305 head only) using putty in the intake port. Here is the charts I came up with:
First one is before intake port mod. Second one is after intake port mod.
It show a significant improvements.
My goals is to do every cylinders with the intake manifold and carburetor attached to achieve the best possible and equal flow rate between the cylinders. This will be my winter project.
