the fast as cast are still a twisted wedge design
you also have to remember that since the valve is canted if down the road you build a stroker and you have a decent cam shaft you will need to buy twisted wedge specific pistons since the valve reliefs are in a different location

AFR's are a good set of heads BUT there are better heads out there for the money. Keep in mind AFR's have the stock valve angle and design. My advise would be to do more research.

i guess everyone is supposed to uy blue thunders 4.3s for their stock block 302s lol

Canfields and tfs tw. Why? Because of the valve placement and better valve angle....they are a better designed platform to make power and give you more room to grow over the stock valve design of the afr's.

canfields off the shelf heads are the standard 20 degree valve angle, they do have a race head that is available in 18... that head serves no purpose on a stock shortblock 302.
tfs tw heads while they do have a 15 degree valve angle they do not make more power then a smaller standard valve angle afr 165 head.
for the afr haters in here they have been developing a canted valve 190 cc head which the last time i saw numbers on it had a 12 degree intake valve and flowed more then the current 205s...
carry on

Don't focus on the "cc" spec of the heads....there's more to it. tw 170 and afr 185's have a similar average cross sectional area size.
I'm not a "afr hater" as i bought a set for my old foxbody. They are decent heads but not end all heads like some people think. Those heads don't exist

check out post 18
guy asked about edelbrock and afr, dude didn't say he wanted a aggressive valve angle, raised exhaust port race head. too often people take poor advice and have a ton o money invested into parts that don't work together

To the OP,
205's are NOT too big for a 302 BUT you have to be very careful choosing a cam at that point. Alot of people think that because you have big heads you need a big cam....that is not true but actually opposite. Guys have been running large heads and small cams for a good while now with great success. (just look at the factory lsx motors) And the same goes for small heads and large cams. The advantage of large heads and a small cam is you can grow into it much better, it will idle better, be more street friendly and it WILL be faster. Most people that tell you large heads will kill your "low end" either have never done it or had poorly matched parts. It's just very important to have the right valve timing when you go with big heads. If you're getting a custom cam I say go for it.
Ya, Im not worried about having a big lope, I have slp mufflers so I hear the stock cam lope.lol. I would love to get the 205s but the extra 400 and change could go twards the intake and stuff. So I hope I wont be dissapointed with the 185s instead.
