nice work as usual

Thank you... got your email...


The intake side is nearly complete... I've got 3 of the 4 ports shaped, just one more to go...



The port walls were given a mild cancave, to better match the shape of the valve while the roof got re-tapered, and the "pocket" removed.




The "pocket" is the dark shadowy area in the right view where the port wall, the roof, and the guide boss all converge


So I've got 6 of 8 intake bowls and seats blended, and 3 of 4 intake ports are now shaped. Along with a good start on the exhaust bowls and seats.



Exhaust port work still to come.




Can anyone tell me why I only cut this head .005" while I cut OST-019 .015"??


More to come
