@toolmanmike , my heads are open chambered #675

And yes i know about loosing compression with these heads.
But maybe you remember the test runs 69 cuda 440 made
The comptession advantage isn't that big in a small motor

#920 vs. #675 Heads "Compression vs. Cylinder Flow"

Make sure you cc it before you final assemble. Depending what pistons you use with those open chambered heads, your static compression will probably be in the 8.5:1 area and with a big cam your dynamic compression might be in the 7:1 range (or worse) @AJ/FormS can chime in.
