I personally do not like the open chamber heads for any cleveland application. Granted the flame path can be better with a open chamber head(ie big block chevy). BUT this is not a chevy. If you really want to go 2V I would jump on these heads:

Go to a dished piston, keep the compression under 10:1 and for the street use a nice .600" hydraulic roller.
Enjoy!
