All are improvements, especially the Roush heads. The original Ford small block head was designed for a 221ci engine, and hasn't changed much since its introduction. None of the factory heads are big enough for a hotrod 289/302, let alone a 351. A head swap on a 351W will produce GREAT results. Building much of a 351W without going with aftermarket heads is a total waste of time. For your engine, I'd go with the 180cc Roush unit. If you have big plans for the future, you might consider the 200, but I'd say the 180 will put a MAJOR smile on your face.  Your stock heads have a combustion chamber volume of 60.4cc, so the 58cc chamber isn't too far off. If it doesn't ping now, it shouldn't with the new heads. Cleaning up a bit of the famous World Products casting flash out of the ports is recommended for optimum results... Good Luck! ------------------

FYI...
The Roush heads come with tiny little 1.25" valve springs, and should be switched out for the cam's matching springs and retainers for anything beyond a stock cam. ------------------

Thanks Mike so you think the 180's would be better choice.I dont see me doing any thing that big to the motor.Maybe a simple rebuild in the future.Do you think the aluminum heads are worth the differance in price.Like the edelbrock RPM heads would be $300 more.I know they save wieght but a dollar saved is good too.I cant buy either right now just trying to save some money to get a pair.Which cam would you use.I was think of the 280H comp cam.So if I went with the roush I'd have to put out another $100 or so for springs and locks.But with the RPM I would not have to upgrade the locks or springs.So that would cut it down to $200 differance.------------------

I like the Roush 180's better than the Edelbrocks for a 351. The 280H is right in the ballpark. You might have to grind out your header openings a bit. The exhaust ports on the World Products heads are pretty large... If you get serious down the road, the Hooker #6208 headers, along with a big exhaust will be a good move. . Good Luck! ------------------

Thanks Mike for your time.Thats one COOL car love the plan look.Speak softly and carry a big stick.I noticed you have stock Ford heads that you ported your self.Would you use the Roush heads on your car too.Will those Hooker headers fit a 351w in a 65 stang.I went with the 1-5/8 shorty heddmen because they fit the 351w really good.I just did the exh this summer.I'd hate to redo it so some.Its 2.5 with a 2.5 H pipe and three cambers flowmasters with turn downs at axles.Is there a better cam for my set up.Thanks Ron------------------

I ported my heads back before there were affordable aftermarket heads available. They are about as large as a ported 289 head gets. They still only measure 155cc on the intake. (Stock is 126) I've got more money in hardware and machine work then what it would take to purchase a new set of the Roush heads... quite a bit more, actually. So, would I use an aftermarket head if I was starting over? YES!!!!!!! The Roush seems to be a good head. The "old" World Products head was good, and this one is supposed to be improved... You should notice quite a difference with these over your stockers. You might also start shopping around for a larger carb when you make the switch. From the site, the headers have a footnote (49)that indicated they ARE indeed compatible with World Products heads. These 1 3/4" units should allow your engine to be quite the heavy breather.

The 6208's will fit a 65. I have a set on my 69 with 351W. Also have the Windsor Sr heads. No problems. Didn't have to remove anything other than the plugs and starter to install. The fit and overall quality is great.I've had them about 3 yrs now, but before I ordered them I called Hooker to make sure they would clear my then C-6 trans. Thy said they weere designed to be able to fit a 65-70 with a 351W and any trans. The prototype car that was used to design them was a 65 with a 351W and a C-6. They even sent me a pic. That combo is as tight as you can get. Anything else is cake. Later, David Cole
