Welcome to the Inliners BRD.
Keep in mind this BRD is provided by Inliners paying members, but you are still more than welcome to use it.
There is a membership form called SIGN UP on the left sign of screen.
With your engine consider .060 a safe maximum overbore.
Zero decking the 250 with flat tops is a good thing to do. Shaving .060 from the head is alot in my mind. Most of my heads get shaved .030 and some get more.
Lumps added to the head intake ports will certainly help wake the motor up and not sacrifice any streetability.
Back to dyno work. Tom
