I finally got motivated to work on the Pro5. I'm moving up to Street Prepared for next season so I get to do some more modifications. I figured porting the head and intake manifold would be easy and quick since I had a spare one hanging around. This is my ongoing photo journal of the work.
The first picture is the stock intake gasket. The second picture is my enlarging of the intake openings. There is quite a bit of gasket there that is not needed. The third pic is the newly "ported" gasket on the stock intake. You can see just how much material will be removed. I used a magic marker to blacken the manifold around the openings so I could scribe the new larger opening.
The other pic is of me slaving away... which is not important right now.
I'll hopefully be able to finish the manifold tomorrow afternoon and start on the head after I get it off the motor.
