[Fot] head porting

[riverside]

Bill Boemler machined the large diameter at the face so
that he could press in a piece of pipe whose inner dia
matched the small side. Results: constant dia port at the face.
He was an SCCA national driver and got tore down on
occasion.  an inspector saw the fix and when he
questioned Bill on it,  Bill said he was experiencing
gasket failures there and the pipe fixed it.  The inspector
bit and Bill did not get gigged.
