Has anyone heard good or bad things about these heads?
they have a dyno article on their website where they put thier heads on a bone-stock 95 gt and the car picked 8 tenths and 4 mph in the 1/4 mile. and with a few other parts like intake and roller rockers the picked up another 7. a second and a half total.
Im thinking about ordering these heads this week, but i wanted other peoples input first.

AFR's are good and so are TFS's. Depends on your application, what stage you buy along with them and how much your willing to pay. TFS has reintroduced their track heats again, look at them too, not just the TW series.

Well I guess no one else is going to reply...so here goes.
The AFR's 165, and 185 are nearly identical. The difference is in the intake valve and intake port, the exhaust is the same on both. The 165 has the 1.90 and the 185 has the 2.02.
Both AFR's out performed the brodix st 5.0 in article done by 5.0 magazine. That doesn't mean squat though, when you look at other people running the other heads and running in the 11's or better.
November 2000 5.0 magazine put a HUGE article "Having our Heads Examined" about Brodix, AFR's, Elderbrock, GT-40X, World Windsor and TFS. Try and get a copy if you can.
Give us an update on what you buy and why. I am curious.

You have to look at what they have done in other places on the car also not just the heads that makes them go into the 11's. If you order the afr heads and the brodix heads straight from the manufactuer, the afr's will out perform any head that you can buy for a 5.0! The heads that are on those 11 second cars are highly ported and rather more expansive than those bought out of a book, so to speak.
buzz...not really you can get in the 11's out of the box with just a lil cleaning up the combo just has to work togther...the AFR are great and unlike most alum heads they have alot of room to port....there's a new head on the way from a company called pro line....there already have one's for the chevys..their about 300.00 cheaper

the AFR 165 cc are 1325 directly, but if you buy them off www.jdsperformance.com for about 75 dollars less. or you could try ebay, but just make sure that it comes with all the springs and stuff.
well if it going to be mild opt for the 165 but the 185's are great for a good build up the differnce is more than valve size also 20 cc more runner volume...and thay are like 10 buck differnce.. should be able to find apair for around 1000.00vfast37922.862025463

damn this post is still here?
well ill give everyone an update i bought the AFR 165's.
i was running 13.80's-13.90's. i put the heads on straight out of the box, a trick flow 510 lift cam and a new timing chain. and the best i have been since was a 12.008 @ 111.94. i dropped almost 2 seconds with heads and a cam. i cant wait til my new bottom end is done so i can do a little porting to them. sad im going faster than all them kids with the bottles and all on motor.
