I'm looking for the intake and exhaust port flow numbers for the SBF 170 and 195cc heads. I can't seem to find them anywhere on the web and was wondering if any of you guys have the data? Thanks------------------

So do you think a set of heavily ported 70 351 windsor castings would be better for power output? Those flow numbers seem really low for a performance SBF head. But maybe that is why they are so cheap???????------------------

Are you talking about the new Pro1 heads or the early dart heads?
Those numbers are for the early Dart/World heads in stock cast condition. They will be better and cheaper in the longrun than the early 351W since they are cast from a ported 351W molds and have screw-in studs, better seats,valves, and guides. They can be further improved with some minor blending and porting.------------------

I'm talking about the ones that were in this months issue of Car Craft. They are the Pro-1 170 and 195cc heads. Just wondering how much of an improvement they'd be over a heavily ported 1970 351w head? The 351w heads are on the car and have been totally gone through and also have screw in studs now, just wondering if the $912 or so would be worth it?------------------

I've only heard about the CNC PRO1, don't know anything about the 175/195 bare castings. Should be similar to Roush 180/200 though. What are you looking to put them on?------------------

DOOE-C casting windsor heads ported,
hydro roller 230-232 @.050, .550 lift, 110 lsa.
weiand stealth intake
650 dp
flowtech headers 17/8 dual exhaust with glasspacks
4-speed
3.50 locker rear will be going to 2.5" exhaust to, maybe bigger carb if the rest of the motor needs it, and maybe some 3.89's. ------------------
1970 coupe restored with the help of my dad. 306 with 650 dp holley, Weiand Stealth intake, headers, mme custom roller cam, harland sharp roller rockers, kb pistons, 10.3:1 compression ratio, pertonix ignitor 2 with matched coil, lakewood bellhousing, 4-speed toploader, and 3.50 9" locker rear.

Save your money and get the AFR 165 58cc heads. You simply cannot beat the port balance and velocity in these heads for the money.
You can get them here with free shipping:

Bluestreek, think the 165 are better for me than the 185, may someday go to a larger cam and go to 7,000 but right now it's 6,500 max. Also I think I'd need the 61 cc heads or my compression ratio would be to high for pump gas, it's already 10.3 with 62cc chambers.------------------

Aluminum heads are a lot more forgiving on compression than cast iron especially since the AFR chambers are contoured really nice. Camshaft selection has a lot to do with it too. Just polish the cnc chambers with sand paper and 11:1 is no problem. I'm running 61cc and flattops on the 333 with no issues. I can run the base timing way up using 93 octane. I thought about recommending the 185 heads but you need to have a good balance of intake to exhaust on a N/A streetable car, and the combination of full exhaust, street gears, and the 185 intake ports will cause reversion problems below 2500 rpms. The AFR 165 will be just right for your 306 with 3.50 gears, 4 spd, and full exhaust. Should put a big smile on your face!  ------------------

Bluestreek, what about the Roush heads? How would they compare to the AFR 165's? I found flow numbers for them, but you need to a subscriber on Fordmuscle.com to read them. I haven't been able to locate the numbers anywhere else. After reading about them, they seem pretty promising too. I'm guessing the Rouch 180's would be the ones Brandon would have the best results on his car over the 200's.------------------

The Roush/World heads are not high on my list. If you absolutely cannot afford cnc'ed heads then the Edelbrock RPM should be your next choice. Everything else will cost more money or make less power per dollar spent.------------------

I wonder why the engine builder I used, who has raced Fords for ever and builds a ton Ford motor's. Told me his first choice is always the RPM heads for street and the Vic JR for the strip. On my RPM heads he did have his head guy do a little clean up and port and bowl work. He said it will the best money I'll spend on the motor.
