1973 340 Cam advice

I'll get the heads cleaned up as there is a lot of deposits and get the valves lapped in. Going off topic would getting the heads slimmed and running a thinner set of head gaskets be worth the time? Or should I just dump it in?

If you are asking about the '73 340, IMHO the answer is absolutely. These had lower compression pistons (4 valve reliefs on the piston tops), and if you mill the heads (slimmed?) and use thinner gaskets, it will improve your low RPM torque, and widen the torque band. Milling .030" off the heads will remove about 5 cc from the head chamber volume.
