D0VE heads are really nice factory iron passneger car heads. Once ported, they have been known to support over 700 hp in naturally aspirated combos and well into the 4-figures (1500+ hp) in blown alcohol combos.

Once fit with big valves and resurfaced, the D0VE heads typically have 73-74 cc combustion chambers. With a flat top piston in a 460, you will be somewhere around 11.5:1 compression ratio. Even with the typical 22cc dished pistons you will still be at about 9.75:1 compression ratio.

Without knowing what you intend for a blower build (displacement, pump gas or race gas, street or track only, etc), I can't make a recommendation one way or the other...but it is possible to make the D0VE head work well in some blower builds.

crap every time that happens I spend a bus load! I want to be in the low ten class when I do hit the strip. Maybe 871 cfm on the blower? And a 300 shot? But must be streetable, and run on super pump. Will run two tanks on rig, one pump, and one trick. With a simple switch to change over. Does this sound possible with stock crank and worked over heads? Merry christmas, I hope everybody gets more h.p.....

A blown 8-71 460 on pump gas could easily run in the 10-second class without the nitrous oxide. The ported D0VE heads could support that no problem, and OEM cast crankshaft could support that no problem. A well planned combo will be important for the longeveity and reliability of the engine. I suggest less than a 9:1 compression ratio, which may require a custom piston....but then again all blown engines are custom builds.

I've been busy tryin to get the final tuning finished on the 400 in my 4x4. Bought one of those hei distributors for it, and ditched the stock ford one. Are you savy with hyper pistons? They said to run the timing 3deg off stock. Is that in the dist. setting, or offset in the cam gear? Thanks fellas....
