Not sure if this helps but mine were almost 6 inches......and displacement meaning cc's of chamber they range between 64-68 cc's

244cc intake volume and 137 exhaust. You need to pay more attention to the runner cross section area than the volume cause the 351c ports are longer than a sbf, or fe, or sbc.

this is not an answer to your q but you might find it very interesting if you have not alreadt seen it. no joke, go to price motorsports and click intake INSERTS for 351;c. sounds exp but makes sense paul md

Yes but you'd have to do some machining.......if I remember correctly it's a 4 V head with open chamber and 2V valves. they are the Cobrajet head, very good head as is best of both worlds for the time.....awesome street head.
