340 upgrades.

good morning all

im new to this site and have a question regarding the 340. i have a 1972 340 duster with the low compression motor. the car is a ground up resto i just purchased but the motor was left alone and just detailed becuase it ran to well. it has 85000 miles. with this milage however i would like to upgrade it at some point to match the rest of the cars newness. my question is what seems to be the best head,intake and cam option for this year motor. this will be basicly a street car to and from shows. i probably will not get into the block (good compression) and will just freshen up the top end for more grunt. at some point ill upgrade the bottom end (pistons etc) to the high compression earlier models but not yet. what package would you all suggest and why. thanks for any and all input and glad to be here.
