For the money and what they advertise for flow numbers and such, these don't look too bad on paper. Someone is using them in a build in the Fox section but I haven't heard how they're working for him yet.


There is also this set, but I'm not sure how well they'd support a 347.


Flotek has bigger heads, but those are their lowest priced. The bigger ones would probably work a lot better:


That's just what I can think of off the top of my head for low price points. :shrug:
Thannk you again LILCBRA,
I am going to ask in the fox group and look in your options!

I have a thread started for this in the Fox forums, you can post in that thread if you'd like, or start a new one. But you might find some info in my thread. I also know that this is a question that has been asked a million times there, so you might do well running a search.

I think your thread will have exactly what I am looking for...

Hi guys,
Finally I decided to buy the Eagle Street 347 stroker kit from Summitracing.
After contacting the Summitracing staff, they mean that Eagle Street is more like a "stock" stroker kit, without forged pistons but with fabric balance and a flexplate included (I have to ask to change it for a flywheel, because I have a manual Tremec T5 gearbox) and the Scat kit it is more for customize it yourself, no balance, no flexplate included.
Do you think also like that? Somebody has this Eagle Street kit?
TIA

A affordable four valve head for a Windsor block would be great. Unfortunately, your answer is the right one.

Flat top pistons with 4 valve reliefs mean that they can be installed in either orientation or side in the engine. Some pistons, domed pistons for example, can only be installed in one orientation. That's what the "4 valve reliefs" in the description means.

Not that they were affordable or anything..... :shrug:


Just for :poo:s and giggles I tried the website in the article - they are no more apparently.

You found it. I do not know how many of these heads, if any, made it into production. An article or two like this is all I remember seeing from around then. A build and dyno test article was what I was hoping for before most of the car magazines got the axe.

I don't remember seeing any dyno results either. I remembered seeing some of these articles way back when, but never heard much more about them or seen any anywhere. It would be kinda cool though. I'm sure some jaws would drop.

I remember seeing an article about a hemi headed 302 too - don't see anything like that anywhere either. :shrug:
