993,487,881,882 appear to be the heads listed in the NHRA guide
CC vol listed in NHRA Super Stock Cyl. vol. list
---993 161 65
---487 161 65
---881 160 60
---882 160 60
I would say 993 or 487
check out the optional cam and piston choices listed :
* = Optional cam lift 401/410
Note A = J.E. #161757 piston uses an .080” dish, TRW #L2403N piston uses a .065 depth and CP #C14-CP piston has a depth of .092. All volumes OK.
You did want to know what NHRA legal head fit the 200 hp 350 engine?
