More to come...

So now that OST-030 is @ the shop getting its valve job, work on OST-031 begins.....

A slightly different angle view on the intake bowls, and chambers... a bit more vertical



This view allows us to see the back of the bowl where it meets the valve seat.



Now when I titled this thread "A delicate dance" originally it was based on working OST-030 side by side with OST-031... BUT OST-031's title has new meaning....




Note how close the gasket edge is to the port outlet roofs... best noticed on end ports, 4 is done, #1 on right is yet to be touched

On #4 (the one done) there was less that .010" to the edge of the gasket. Typically I have over 1/2mm (.0197") or even more!
