My recent flow bench test of last fall show ( moving a head around on a Bore adapter) that your better off even with the Bore size of a .060" over 350 motor to either run only a 1.96" Intake valve, or a 2.11" valve with limited lift if your running a pre 1970 head casting.
The deeper chambers of the post 1970 heads will not cut into the added flow numbers of running a 2.11" valve at a lift of up to .450" if I recall my numbers right.
If your 350 build needs to drop some compression then adding the needed Intake valve chamfer to the top of each Bore is a good help!
