Heads for 72 340

[gunmetal]

I have a 72 challenger 340 with .030 over aluminum pistons, block has been decked (pistons stick up about .023) and I'm being told running close to 10 to 1 compression, Street Avenger 650 carb, Eldelbrock RPM performer intake, comp cam with intake 224 exhaust 230 duration .050 lift.  All this with stock 360 heads.  I'd like to upgrade the heads, can anyone recomend something for me.  I want this to be a daily driver that runs on pump gas.

How about cost if I just upgrade my heads?  I have set of Titanium valves that I got when I purchased the car I'd like to use them if I can.

the best production head I have used is the 308 casting ported with larger valves , it makes  a lot more power than a X or J
 for aftermarket heads I am not a fan of the Eddys , bad core shift problems , W2 /W5/ W7-8-9 all make huge poowr but are very expensive by the time you buy special intakes , rockers , headers & valave covers to fit them
