Now if you were talking about stock L92 piston, rod, and crank then 9.5:1 is not going to happen. Because the L92's come from the factory at 10.5:1 with the 70cc heads.

But you are talking about a L92 Stroker (414 to 418).
You'll need to match up the -xx Dish size to the ported heads you plan on going with.
The reason I say "match up" is some of the Ported L92 heads are shaved .030" or so to get them down to a 64cc chamber. Where some are full deck height with the 70cc chambers.

When Richard at WCCH CNC's the combustion chamber it adds about 6 cc. Give Richard a call. He can definitely set you up.
