Reworking voodoo heads

[Voodooo]

Interesting. I will take pics tomorrow of that
I was advised these where voodoos. Maybe you are correct

The voodoo heads have 4 bolts for each of the 2 center exhaust ports. That's ONLY on 5.2 heads. That's the easy way to tell them apart from the 5.0 heads.
Also the valves are larger on the 5.2
The coolant passages are unique on the 5.2 vs 5.0 heads
The combustion chambers are also different on the 5.2.
I'm sorry but I think you have 5.0 heads, possibly boss (road runner) heads.

And here I have thought these where voodoos

Do you have a picture of a stock voodoo chamber

Notice how your heads have a dimple between the exhaust valves? The 5.2 doesn't have that.

Ford put 4 bolt holes on each of the two exhaust ports. This was done so the assembly workers couldn't put a 5.0 exhaust manifold on a 5.2.
A 5.2 heads has different ports, chambers, valves, valve train geometry, coolant passages. Etc.

I saw the pic
These are not voodoos

This is what I feel like

Don't feel bad. I mean you did an awesome port job!
The heads you have may be boss 302 heads. Those are factory cnc ported also.
Did you pay a lot for the heads?

 

[Gremlinsteve]

No
There a local customers heads
The exhaust is amazingly strong

 

[Gremlinsteve]

I'm thinking there a boss 302 head maybe. Pre 2015 design?

I'm curious if you can stuff or fit Voodoo valves in coyote heads.

 

[Gremlinsteve]

I found the seats in the coyote won't handle much over stock sizing
It can be done yes. But you would shroud the valves somewhat and you might needs to start installing new seats

This is my thought too. The work is nothing short of amazing and done in a short time frame. Should speak volumes about his operation here despite the fact some how the heads appear to be mixed up!

 

[Voodooo]

5.2 heads on a 5.0 block would be shrouded.

 

[Gremlinsteve]

Sure would
I'm not a believer in the plus 1mm ferrera valve In them either
I have some pics showing how the shroud at low lift

LOL. Yes you did a good job on those heads. If you feeling like the picture you posted, I know an easy way you can redeem yourself. Get ahold of some GT350 heads, port and polish the piss out of them, and post before and after flow bench tests. Bam, you are redeemed. :cheers:
