best head for 1972 chevy
 
What is the best head to use on the 1972 200hp 350 chevy? This is for a stocker application.

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?

Yes Adger That is what I am looking for. I was woundering if any one has a tendency to out flow the others. I did know about the optional cam that is part of the reason for looking at this one.

The 487X is the best choice.

I'll 2nd that. Have very good luck out of the 487 over the years.

From working and flow testing all of them back to back. All of the casting can flow exactly the same when the same work, valves and valve jobs are used. The smaller exhaust ports make more power. The 487X works better with larger cubic inch motors (350 and above). I hope this helps.
