Default L92 and LS7 size?

How many ccs are L92 and LS7 heads? I searched for a bit and all the terms are too short to get picked up...

If I have a 402 Iron Block with -18cc dish pistons, what compression would I have with both heads?

Im looking into a 'budget' turbo project and want to know what my head options are...

How much can you mill the LS7's. I heard the L92's can only go to around 66-67cc's comfortably? Someone please correct me if I am wrong.

The chamber on the L92 is 70cc, and you can take it farther than that. The problem will be is you can mill them farther but at a point the intake manifold will not fit anymore.
