DIY Crack Checking?

Just a thought; What about selling all those heads and going with a set of EQ la bolt pattern heads? A set of virgin castings is $ 612 to your door from Jegs. If they would work with your project, you would be in good shape for head flow, the numbers i see in articles are very good with minor work.
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.
