Are these any good heads. They are on my 429 in my street legal pulling truck. I would like to build a class dominating truck. I'm not sure if i should work these heads or get different ones. I also think i may stoke it out to a 514 or 540

 

Those heads are an open chamber design and prone to detonation. Are you restricted to stock heads?

 

No. the rules are kinda vague. Says i'm allowed 3 mods. I already have L&L headers. and a carb. But they dont usually even pop the hood....so i was thinkin a good set of heads(good production), intake/carb, and my headers , w a mild cam

 

Do you have to run a stock(production) intake? If so I would run a set of DOVE or D3Ve heads with cobra jet valve size and good port work.

 

I can run any intake i want. For the street class no one really looks over the engines

 

if you are looking for factory heads then the cobra jet (D00E) heads followed by the Police Interceptor heads (D20E not V) heads are the two best choices especially if you are stroking the motor. the Cj heads have huge ports, huge valves and with a decent porting job can make decent hp. the PI heads have slightly smaller ports and smaller valves but are a good choice if you find a pair. either head pops up on ebay quite often, but are usually worth a bit as they are in demand by mud pullers limited to stock heads.

the D0VE, C9 or C8 heads are also good choices if you port them properly and install larger valves. re-incarnation website has an excellent how to section on doing this. also the D3VE heads port wise are pretty identical to the D0VE heads and are plentiful and cheap and can suppport some decent hp properly modified.

then of course there is a lot of aftermarket heads out there that will out of the box outflow and outperform even modified factory heads and come with decent valves, springs and hardware already installed for a bit more money than fooling around with factory heads.

good luck.

I found a set of D0VE-C heads for 200. they are bare though. What does the c mean. is that worth it?

 

That seams high for bare heads. Have they been cleaned up at all?

 

They are all cleaned up. All ready to be assembled

 

If you live close by, I have a set of D3VE that are stock that I will let go for $100. I live in north central Georgia.

 

what are D3ve heads?

 

they are the casting revision following the D2VE heads that you have. The are pretty equivalent to the DOVE heads with bigger combustion chambers.

 

O , lower compression ratio? 9:1?

 

Yes they have a 92cc combustion chamber and 8.5:1 compression. From what I understand these heads can be used to make a 425 - 450 hp engine with bigger valves and some port work.

I got this excerpt from 460ford.com :

HOW TO BUILD A 425-450HP 460ci

The request for information for a mild 425-450hp street motor comes up weekly, so I thought we'd compile a list of parts that will accomplish this goal. Obviously, there is quite a bit of room for interpretation and variance on parts, but a good SEARCH will help sure up any remaining questions.

750cfm Carb
Edelbrock Performer, Performer RPM, or Weiand Stealth
Hydraulic flat tappet cam with approx 215-220* intake/225-230* exhaust duration. Lift should be in the .525"+ area to take advantage of the quicker lobes allowed by larger diameter lifters in Fords.
Examples would be the Comp XE262H or Lunati 61602
Compression should be around 9:0-9.5:1
Stock rods and crank can be used with good resizing and good bolts used

Heads can be DOVE or D3VE
Exhaust valves should be increased to 1.75" size
Intake valve size does not need to be increased at this level, stainless valves are suggested over heavily used stockers
Port work on the exhaust side should be considered MANDATORY at this level. Thermactor removed, bowl blended to the larger seat, casting flash removed, exhaust bolt boss flattened. The better the work, the better it will run. To get to a real 450hp level, it would be very beneficial to at least clean up the intake side, the seat to bowl blend at minimum. A good 3 angle valve job is mandatory. A D3VE head does have enough potential for this build but may require more short turn work on the exhaust side to match the DOVE. An aggressive cam like the Lunati probably requires the screw in stud conversion on the D3VE as well.

Exhaust should be minimum 1 3/4" headers to dual 2.5" pipes with good flowing mufflers. Manifolds will absolutely not allow the engine to perform as expected.

Roller rockers are not mandatory, but suggested. A HV oil pump is not required at this level, as the RPM level doesn't dictate loose tolerances. Standard .0025 and .0030 on rods and main should work fine, a bit tighter would probably be fine as well since the motor shouldn't see anything over 5500rpm.

Good machining and port work should allow a motor like this to last forever, creating a solid 425-450hp at around 4500rpm and 520-530ft lbs near 3500rpm.

 

thanks thendrix. very helpfull
