Looking through some notes.....
1970 T/A head, 2.02 valve w-11/32 stem.
Basic full port and polish, remove pushrod bulge.
Full disclosure, I didn't port these heads, they had been done previously to me reworking this engine combo.
After I freshened the valve job:

Average for cyls #1 & #2

Lift---IN flow
.100---66.0
.200--135.9
.300--201.0
.400--237.7
.450--251.7
.500--258.5
.550--252.5
.600--249.8
.650--249.5
.700--249.5

I used a cam with about .625 lift with those heads.
