SBF Cast Roush heads

[triracer67]

Got a set of cast Roush heads, appear to be in good condition. Do the make good power, and are they worth keeping?

 

[DirtDonk]

Do they have a model number on them? Did Roush make different versions?

 

[Bitch'nBronco]

Do you have pictures?

5304d. They say Worlds on the inside. I guess I lost my ability to post pics…

 

[DirtDonk]

Are they cast iron, or cast aluminum?
Sounds like they might have been made for Roush by World Products.
But they do say Roush on them somewhere?

 

[triracer67]

Cast. Odd. They say worlds on the inside, and Roush on the outside by exhaust outlets.

 

[DirtDonk]

Then they were sold to Roush in a semi-private label, sort of way. Not unusual, though seems like Roush would’ve had their own made rather than using an off the shelf part.

I’m just rambling on though. Don’t know anything in depth about the relationship history of the three companies. Ford, Roush and World Products.
And because it says “Worlds“ with a S, that seems unusual too. But they’re using the same, or at least a similar part number to actual world products heads.

Didn't read the article but it says Roush had a relationship with World heads.

Sounds like they're a decent set of heads

I have a set of these cylinder heads on a 410W. If they are those heads, they are World Products Roush Sr. heads. The are 200cc intake runner, usually 64cc heart shaped chamber. I have 2.02 / 1.60 valves in mine, mild pocket port and bowl blend. They are capable of flowing 270-280cfm on the intake side I was told by my machinist. They make a good street strip head. Good power in the 2000-5500 range. In other words a good drivability head. I think the exh port is raised .5". Spread port on the exh, so you can run larger primary header if you want. Back in the day you could get one of these heads brand new bare casting from Summit for $400

Seems like no one local wants to purchase them. I guess I’ll hang on to them and maybe use in the future. Thanks!

 

[bigmuddy]

Wish I had seen these before I rebuilt the GT40 heads!

Triracer whats the ask on these?

 

[triracer67]

I was asking $500.

I got 351 heads i pulled off my 302 if you want them. They need work beyond lapping but free. Made the truck sound like jiffy pop
