What about milling the tops off the pistons to use the 1008s. This would Simultaneously reduce the size of the eyebrows? And that would keep the compression up.Plus the intake and head ports would line up better.
I have run as little as .023 quench, with no kissing. I am currently running .034.
This would also give you an opportunity to put the dome where it does some good, by milling only those portions of the piston tops, that are under the pads. This also would keep the compression up. The higher the static compression ratio, the bigger the cam you can run, before the bottom gets soft. This is only really important on a street runner.
