The D0VE-C factory iron cylinder heads are the most popular of the 429/460 heads. Contrary to the above post, they are a great
factory iron cylinder head...definitely among the best mass produced passenger car cylinder heads of the era.
The intake port architecture is second to none and these heads can flow great intake numbers for what they are as cast and with a little bit of cleanup.
Valve angles are great and the combustion chamber is great, spark plug location is great, and these heads, on a .030" overbore 460 with flat top pistons, make about 11.4:1 compression ratio.
The exhaust port is poor flowing as cast (all factory 429/460 iron heads are), but fortunately they can be ported and this transfoms the D0VE heads a la Jeckyl and Hyde.
Well ported and prepped versions have been known to support 600+ hp on 460's and over 700 hp on stroker engines, naturally aspirated. Oversize valves are available, 7/16" roller rocker studs screw right on, etc.
Making use of the proper head for a given application is important when planning your engine combo. Whether the D0Ve-C head is right for your build or not depends what you want to do.
