Those heads have had only mildly positive reviews, and really don't seem to flow any better than the old Windsor Sr.'s. Actually there was an article saying that they have to redesign the exhaust port, I believe it was, because everyone has been disappointed with the flow numbers. But, they are relatively cheap if you buy the iron version.
Another negative is that you would have to port them/ clean them up because they come fom the factory with a lot of flash, in pretty rough shape. A lot of people have commented that the valvetrain components arew not that good either, so people buy them bare and then add the components that they are comfortable with.

Personally, I would probably buy Twisted Wedges, Canfields, or a set of the big AFR's like the 185's or the new 205's - you'd probably be much better off.

Regarding the horsepower, I'd imagine you'd be in the 450 HP range, I really think that 500 HP is a stretch.

I really like what I read about those heads.They are great low buck heads and better for the money then rebuilder your heads.But with your set up I'd go with a better head.Like 69Stang said,the edelbrock rpm heads look good too.

If you go for the World Products heads, be sure to clean up the castings with a grinder before using them... They come with tons of casting flash that needs to be removed. Some of it is so bad that it could even break off and get ingested by the engine.

Go to...

for a tutorial on how to clean up a set of heads. There are tons of pictures, and it's great info.

In my opinion this basic work is needed on about ANY set of "as cast" heads, stock or aftermarket. If you want a set that can be taken right out of the package and put on the engine, buy the AFR's. They come with good hardware and EXCELLENT port work right from the factory.

Good Luck!
