It came factory with 275HP.
The 3947041 heads are decent heads.
How much power are you aiming for and then I could list a combo for you if you want.

i would like anywhere from 350-400. also , because my car is so heavy. I want a ton of torque. This car is most likely around 3000 maybe more lbs. its a 72 impala 4 door sports sedan.  I need good acceleration to get up and move in this boat. Daily driver and weekend cruiser.

If you do use one of the sets of heads you listed use the 041 heads they are decent heads.
What is your budget like and then I could list a combo of parts for you.

i have the most minimal of budgets. alot of work will be done by me researching and doing things myself. junkyard finds and such. what little money i do have to buy new parts i will. this is something i know will take awhile to get things just right. if i have to save for good parts i will. there is no rush on this project..

Do you know if the valves in the 041 heads are 2.02/1.60 or 1.94/1.50.

Yes use a measuring tape and measure the valves be sure to measure across the center of the valve if it is under 2 inches then they are 1.94 and if they are 2 inches then they are 2.02 valves.

when u say across the center do you mean width wise from the ports that are side by side or just one port at a time ? maybe if you have an illustration or can direct me to one to get the measurements right.
