440 EZ-325 CNC Questions

JBC426, thanks. Nice photos.

IQ52, I was doing a lot of reading over the weekend. I am now finding a lot of articles on all these heads. The nice thing is talking to people that have already tried many of these heads.
I was thinking about the chassis, that will come in time. I wanted to have good heads, now that I have a good bottom end.

MidTexCuda, the 440-1 heads are interesting, I was reading about them. Only info I did not get is if the exhaust ports are in the stock location.
