As is was bright and sunny today I decided to leave my seat re-trimming for the moment and go out side to play with some dirty bits ( no not rude things). I bought some carbide burrs (like forary files) in the week to do my head porting and had a scrap head lying around so I thought I'd give it a go. How hard can it be? I set myself up a makeshift workbench in the sun, got all my tools out along with the spare cylinderheads for the "Lee". At this point I thought "Sod it, I won't bother practising I will go straight to work on the V8 heads."
Here's how they were before
I stole a bottle of nail polish from Jo and painted the area arund each port. Then I bolted an intake gasket to head and used that as a template and scribed the nail polish so I know how far to open the ports.
Lovley colour, don't you think.
Then I used the burrs to open up the port openings to match the gasket, tapering in to meet the port's original size about 1 - 1.5 inches into the port. Any lumps or imperfections were smoothed down and any square angles in the casting within the port was rounded off. Now I need to polish the ports as the burr leave a harsh surface that will attract a carbon buildup like the Bechams attract the papperazzi.
I couldn't get a good picture of the valve bowls and guids but here are a few of opened ports.
Will update as progress occurs. 8)
