OST-035: Silver Blaze

[oldeskewltoy]

Back from the machine shop... surface was machined .002", isn't that pretty, and ready to accept a metal gasket.




Now carrying the exhaust 3 angle(bowl closest), and as you can see the intake 3 angle is still good, so I used a tiny bit of lapping paste to get the intake seats and valves mated



Clover lapping paste on left, Permetex/NAPA valve grinding compound on right... think of the Clover as a polish




that polish helped reveal..... a tiny bit more performance may be available with a back cut on the intakes. That is for another day/head.



the red arrow is pointing to the top of the seat-valve contact point, so the dotted green lines represents a bit of room for a simple, clean back cut.



Finally, my client asked me if I could do something to better accommodate his use of ARP studs....



Look back at the first pic in this post to see the bolt hole before.....


more to come.....
