What do you think of my build? 318/390

Treb, with those chambers at 69cc you will actually be looking at more like 8.7:1. Get them milled .030 and you will be more like 62.75cc and 9.26:1

Couldn't I just used taller pistons and a thin gasket to keep from cutting the heads?? I have to buy pistons and a head gasket anyway. I'm not worried about quench because of the stroke volume. I also read that stroke volume also increased the CR??
