I just bought a set of dove 429 heads and was wondering how good they are compared to early 460 heads. Is the difference like the 2v and 4v 351c heads ? Like on a 500 h.p. 460 using 460 heads.... and then you switched to the dove heads- thanks.
DOVE heads are just as good as the C8 heads. Properly ported and bigger valves and you could push 600HP threw them. There is only one head for both the 2 or 4BBL engines along with the 429/460 both used the same heads.
The base 429-460 heads are pretty much identical..The changes come with different years not the different engine size...Comparing the CJ heads to the base units would be more like a comparison of the 2V-4V cleveland heads with the huge difference in port size.
To max the heads out you need to convert to screw in studs, gudeplates, and install 2.19 or 2.24 intakes with 1.72-1.76 exhaust valves. Also need alot of port work on the exhaust side. They can support up to 700hp if worked up properly. The best other option would be figure up the total cost involved in the DOVE's including machine work and then consider buying a complete set of Trick Flow street heads. Think they go for about $1,900 ready to go. Chris
The base heads already come with screw in studs.You will need to have the stud bosses milled the thickness of your guideplates and install the guide plates with some studs that allow you to adjust the valve train instead of the postive stop studs....
Reworked meaning has anyone done a valve job, maybe milled the heads for straightness, new valve springs? If not, port them mainly on the exhaust side, have CJ size valves installed, screw in studs, stronger valve springs. Mill for straightness and deburr the oil return holes.
