I bought an engine to rebuild. It is a 1971 429(D1VE-A2D) with 1973 heads(D3VE-A2A). Are the heads any good for decent horsepower and what would the Combustion ccs be? Can these heads be modifed or should I buy a boat and use the heads for anchors?

With enough massaging, oversize valves and additional support hardware all mounted on a stroked 460 block they can make 650+ HP! What HP/performance level are you looking for?
... and what would the Combustion ccs be?
>>>According to some sources, the D3VE-A2A heads have a closed combustion chamber. I've read that they have as small as 91.4cc chamber and that they could be as much as 97 to 100cc. The general consenus is a 95cc volume. You may need to simply measure their volume. When stock, they were outfitted with 2.08" intake valves and 1.66" exhaust valves. A 1973 460 was listed as having a compression ratio of 8.0 to 1.
Can these heads be modifed.... >>> Sure. Anything can be modified - with enough $$$. Whether they can be modified to the level of performance you're looking for within your budget hasn't been determined yet.
....or should I buy a boat and use the heads for anchors?
>>> I'd say their use as anchors would be a tad bit "overboard"... 
Tell us more about your plans and more folks could help & guide you with spending your $$! Ryan

The heads are standard 429/460 heads, D3 being open chamber.http://www.reincarnation-automotive.com/chamber-comparo-pics-page-linked.html ------------------

Gary,
In your link, the pics of the closed chamber DOVE-C and the D3VE-A2A chamber appear to me to be VERY similar, whereas the D2VE-A2A head chamber looks to me like an open chamber style.  NCREBEL,
Notice that at Gary's link, it indicates the D3VE-A2A heads have a 92cc combustion chamber volume.  Ryan [This message has been edited by Ryan Wilke (edited 11-17-2006).]

The 1972 cylinder head (production) was called a SWIRL COMBUSTION DESIGN and is to be avoided. The 1973 photo may be incorrect, but did go to open chamber in 1973 (reduced CR and EGR).   There are subtle diiferences. Look around the intake valve. [This message has been edited by KULTULZ (edited 11-17-2006).]

Could the 73 heads be shaved? How much would that help?------------------

It will be a cruiser to have fun with on the weekends. Of course, I want to be able to smoke the tires sometimes and scare the rice burners. It will be backed up with a fourspeed Toploader and 9" 4.11 posi.

-HERE- is a fairly good description of the 1971 and 1973 cylinder heads. I would keep them and find a piston to raise the CR to about 9:1 for the street.A cleanup cut will be OK but too far will shroud the valves.

A 1971 429 with 1973 heads is what I have in my 1978 F-150. For a weekend cruiser i would go with an RV cam and an Edelbrock Performer (not RPM) intake. That's my setup and I have put 225,000 miles on it.This motor, fresh, in a 1969 Torino will scare you. The Rv cam works best in the range I call "stoplight to speed limit" which is where you will be cruising 95% of the time. Tracy ------------------

OK ya'll have gave me a lot of info on the heads. I am going to port and polish and shave them .020".
As far as the block goes,(D1VE-A2) How should I go about buying the pistons? I have no idea what year car or truck it came out of. What would you do? Is there pistons with higher CR fot this engine?

Check with your machine shop. They should have a few catalogs for pistons with CR info. Usually a good machine shop can get all the stuff you want and make one package price cheaper than if you bought parts from five different places. They will know the brands that they don't have any problems with. Tracy

Kid Vishus, Iam down around Allen and Sons BBQ. Click me an email and we'll have coffee.([email protected])When looking for parts, do I ask for "1971" 429 pistons?

If you ask for that year specific piston, you will get pistons that give the same compression ratio as stock. A 429 piston is a 429 piston regardless of what year of motor it was intended for. More than likely, you will end up with flat tops in the motor, and those are relatively cheap and easy to find.However, I have no real good idea of where to take any machine work in this area.

Kid, There is a great shop in Mebane one street over from US 70. It is across the street from Suntrust Bank. Shoot me an email, I would like to meet you. I may need help on my Torino.

Yeap that's the one. I remember now why I haven't been back. They screwed my 390 block. Didn't finish bore but stuck pistons in anyways. Major deep scaring. Thanks for reminding me.

You are correct and I was mistaken Ryan. The 72 was Open Chamber while the 73 is actually closed chamber, but with a larger chamber than the 1971 and prior year heads. I apologize...
