CC size, rocker design perhaps. Do you have the full number? Check it against this. No guarantee on this info, but it's a sticky at the top of the SBF forums.

mcdonaldm is gaining momentum as a positive member of FTE.
the two biggset differences between the DoVe head and D3VE head is as follows

- DOVE heads (and the C8 and C9 head) had 77 cc chambers. the D3VE head has 95cc chambers. basically the same shape, just that the D3 are deeper.
- DOVE heads have screw in rocker studs c/w rail style rocker arms non-adjustable. the D3VE head has bolt down rocker arms pedastal style non adjustable

the valves are the same size (2.08" intake, 1.65" exhaust) and for all intent and purpose the ports are the same (slight difference due to larger chamber of D3 heads) the valve lenghts are different between the two.

the DOOE heads (the Cj/scj heads) had huge valves (2.25"/1.76") and intake and exhaust ports. way too large for a street engine unless max rpm is your goal. the D2OE police interceptor engines had 2.19 intakes and ports sized inbetween the cj heads and the D0/D3 heads. probably the best all around street heads if you can find them. the D2VE heads are good boat anchors so won't even mention them.

the main hp gain from changing the D3 heads to the early heads is in the compression bump. the ports basically flow the same.

Yes they do. the later D0VE's also have the thermactor hole drilled in them just like the D3's do.
