I'm torn between afr 205s or 185s. i'm buying new dart 302 and boring to 331, holly or trickflow intake maybe a ported cobra (i would rather have a ported cobra because of the looks) and a custom cam. i am also going to add a supercharger that will give around 10-15 psi, 42lb inj. 75mm TB, 80mm MAF for 42s.

So which heads do all of the experts suggest?

If it has to be afr's, use the 205's. Out of the manifolds you listed, the TFS R is most ideal, but a holley will work. A victor manifold would be great for this combo, but its not for everyone as it has its downfalls.

42# injectors are no way NEAR enough. Put a big injector in and tune it with a PMS, tweecer or any other good tuning device.

Like Grn92LX said, you need the 205's, forget the 185's. Trickflow manifolds will mate to the heads better port alignment wise. The Holley has a rather high port heigth in comparison to a stock port location manifolds. I wouldn't bother with a ported cobra for that set up, it CAN be(not always is) restrictive on a 302.

Grn92LX is right about the injectors as well...

205's seem rather big for a 331 even with a power adder. I guess if you don't mind all of your power at 7,000 rpms than your fine.
I am also going the s-trimmed, dart 331 stroker combo except i'm using AFR185's since its a daily driver.
I third Grn92LX on the bigger injectors. Your going to have to look at close to 55# injectors making around 580rwhp depending on boost.

Yeah, I hear alot of good about the trickflow intake and the systemax one seems decent too. What does everyone think about the typhoon intake, doesnt it replicate a big name intake? Also I think that the 185 would be better for the street as well.

i would opt for the vic jrs and save some money. they work great on my 331.

as for the intake, i wouldnt go much less than a TFS R or and edelbrock vic jr intake. with the vic intake, your cubes will lower the rpm range and some more with the intake spacer (if you use one).

grn92 is also right about the tuning system.

Everyone always recommend what they have lol. go with the 205's. 331 will work fine with 205s and boost. Look at MM@FF... pulled out over 1000 HP with a turbo, 225s, and a 331.

AFR 205's, Low impedence 55lb injectors, get a tune on a dyno with a chip, and get some nice forged internals with ARP bolts...
