The build will be a low buck, mild hop up 318. I was hoping to find out just what I have to choose from, as in, if I find multiple cracks in any of them, oh well, get rid of them and they're out of my way. Then if I still have 318 and 360 heads to choose from, maybe I'll start another thread..."318 or 360 heads on a mild 318?" (seems to be one of those Great Debate questions! lol) Thanks guys.
