Do they? What makes you think that? I am looking into buying some too...Maybe you can give us your insight where poeple and as you stated "AFR believers" tell us that the porting sucks. I just want to buy something that works.

afr's Afr heads flow terrible out of the box, if you spend a bunch of money on them at a good reputible porter then you'll have an awesome set of heads. Cheaper to go with trick flows and have them ported.

A friend is looking to sell his AFRs so he can put AI ported stockers on his car.
Most of the AFR love comes from believing in marketting and a reputation built before the LT1. They did not keep pace with the LT1 and recently redid their entire lineup to try and compete, basically an admission it was all grossly outdated. My understanding is that till recently it was all like 60-70s era ports they bought from Brownfeild. New stuff the "eliminator " line is untested.

Has anyone here actually flowed a set of their "out of the box" 210cc comp eliminator heads? Or are you just repeating "hear say"? Just curious if anybody here has any data that proves their heads are garbage out of the box. Seriously, I am pretty sold on their heads...but I'm always looking for better results.

I'd like to see what AI will be able to do with the Dart heads in a couple years. They supposedly flow in the 260s out of the box as cast which isn't bad. I was considering buying a set but it looks like I will be able to get my LPE heads fixed and have new Ferrea valves and springs and all for well under $700. Just the Dart LT1 castings would of run $420 a piece bare, and there wasn't much point in buying them when I don't have the money to send them out for porting and the LPEs will flow better than the as cast Darts.

P.S. The reason AFR created the elininator heads was cause their older ones were designed very soon after the release of LT-1 cars way back in late '92. The new eliminators are using LS-1 style valves, springs, and retainers. This is what super chevy has to say about them.
A clean sheet of paper approach to port and combustion chamber designs has boosted efficiency levels dramatically with smaller cross-sectional areas flowing 5-10 percent more across the entire curve for increased airspeed. AFR is the first company to incorporate "Gen III" technology into their 23 product line by fitting them with 8mm valves, and lightweight springs and retainers (a 50-gram weight reduction per valve/spring/retainer assembly), which reduces valve float and improves high-rpm power and reliability.
Sounds like that whole weight reduction thing is a good idea for anyone who wants to spin their motor to 6800 to 7000 r's. Just my .02 -Chris
Oh, heres a link to the article I pulled that clip from: http://www.superchevy.com/technical/..._products.html

The 210s are good heads. You will be fine with them. The smaller ones like the 195s are not as good generally compared to ported stockers or trickflow. People have made good power with the larger ones though. Do some searches on the camaroz28.com site.
