They are junk. They have an open chamber that causes the engine to ping bad because there is no quench area. If you want a low compression motor get a set of D3's. If you want to raise the compression get a set of C8's,C9's,or D0ve's.

hi Richard, talk to someone who knows don't listen to the others. the 1972's are a very unique head it is the only year ford made an open chamber design,starting the lower compression years. i have run these heads for many years on a block that has been bored .060 over running dished pistons with a compression ratio around 9.6:1 and have had no problems!! people assume that these heads are junk because they are open chamber but that is just not the case. my H.P. was around a very conservative 425 ponies. you still need to port the exhaust, getting rid of the bump helps out in any of the big block designs. going with the d-3's will lower your compression lower than if you were to use 1972's.. these heads have lasted well over 110,000 on a nicely built engine that had seem every day driving at and above 4,000 r.p.m.'s since it was first started. if your not going to run the sheet out of them why build an engine!!!!!!
so if i were you hold on to them there are not many of those heads around. C.J.

I do know what I'm talking about. I have a set of D2's on a 429 with flattops now and it rattles its *ss off. I made the mistake of putting these on in place of C9's to lower the compression and it rattles just as bad now as it did before. I have a set of D3's going on soon. If you are using dished pistions and D2 heads you probably have a comp. ratio of 8.6:1. You need flattops to get 9.6:1 with 92cc heads. D3's have the same cc combustion chamber as the D2's so he won't lower the comp. ratio by switching. I agree with everything proeliator said and I did leave out the D1 heads on my first reply.

If I remember correctly, D2VE heads have closer to 98 or 99 cc chambers, and a "bathtub" shape, resulting in low compression and almost as bad of a detonation problem as Open chamber heads on a stock 400. The D3VE is a much improved design, will actually raise compression a hair, and improve detonation resistance. IMO, you should stay away from the D2's and either get D3's or D0's(or equivelant).

well everyone has there right to their own opinion, that's cool, i have never had a problem with this set-up and like i said in my post they have 110,000 THOUSAND + miles and have never had a problem. everyday beating the crap out of it..
and my compression is 9.6:1 i know this... i can see why the other guy had spark knock you can't run flat tops with these heads ( D-2 )
all i can tell ya is use your own judement, if i can use this set-up with no problems it looks like someone may not have the right knowledge to make theirs run the same..
this is all i'm going to say i'm not going to get drawn out into a shouting match about what i know and what other say also.
take it easy Richard, hold on to those heads. C.J.

Listen Richard, Cj was right in that there isn't any point in getting in a pissing contest over this, and we are both trying to help you. My final advice is to re-suggest that you talk to some 385 head specialists and see what they say before you make a mistake you'll regret. As much as I hate to see this bad info getting out...I (we) made our counterpoint so I'll leave it well enough alone. 'Nuff said.

Just curious, you said you were certain you are running 9.6:1 compression with dished pistons and D2VE heads. How do you know that it is 9:6 to 1?? Have you cc'd your heads and the dish in the piston? Do you know what your deck clearance and head gasket thickness is? Help me out here, I'm trying to do the math with my compression ratio calculator and known Ford data for these heads and dished pistons and it's not workin for me.

There is always going to be somebody who says it works for them, no matter what the common consensus is.
The above poster is the only person I have ever run into that defends the D2 heads. Everybody else (including some very savvy people on the Network 54 board) say dump them.
My theory is that "half a million people can't be wrong."
It's great that the D2 heads work OK for him, but how does he know the D0VEs or D3s won't work a lot better?
