Well assuming the 400 will be .030" over, and then also assuming your 1974 350 cid # 46 castings where no more then 96 CCs in stock form, you then will need a maximum of 116 CCs of volume total at TDC to have a 9 to 1,compression.
Some normal CC numbers to add to your chamber volume are Head gasket =9.4CCs. 4 valve notch Pistons = 6.7 CCs. .023" deck clearance = 5.097 CCs. Top Ring land volume= 1.5CCs. And lastly the valve job done to the head likely added 1 to 1.5 CCs to the chamber volume. Milling the head .030" will knock off 5 CCs.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
