To the best of my knowledge there is no way to enlarge you combustin chamber for lower compression. You can mill heads to raise compression, but I cant see how you could un mill them. If you want to keep your heads get some low comp pistons.

I don't know about that, I am looking at LS6 stage II heads, but I wanted to keep the LS1 10:1 CR and Patriot said they could build me a pair of LS6 stage II with 67cc chambers, therefore going from 10.5:1 to 10:1.

So I guess that enlarging the bowls is possible, perhaps only to a certain degree.
