Hmmmm, I missed un update.... (2 weeks ago - end of July)

The machine shop took nearly 3 weeks to perform the 3 angle, and back cut the intake valves....


but their 3 angle looks quite nice



The arrows are pointing to the seat/bowls that are not quite to size. Now that the valve job is done, the finishing touches are performed and now all the intake bowl/seats are @ 26.5mm, and all the exhaust bowl/seats are @ 22.0mm.....




Next... setting up the head for checking chamber volumes



and I've got one @ 37cc, and 3 @ 36.8cc...



I have a wee bit of work to do on chamber 1,3, and 4......


I'm holding off on the head cut, and final chamber volume until I know the actual deck height. The client purchased 9.5:1 pistons, and a .8mm gasket, AND wants me to keep static @ 9.5....



More to come.....



NOW a current update 8/8
