AFR flows 258/192 @ .550

LE3 270/190 @ .something.

AI Fully ported CNC 190cc 27/194 @.550

Just looking around right now, but if anybody has any opinions that be great.

The Bottom End will be a Forged 355.

Do not go with that size AFR. You will make more power with the ported stockers with either AI or LE. Both do great work, so you really can't go wrong either way.

I was looking real hard at those AI 190's If you go that route I will be very interested how they turn out.

Wouldnt do AFR. I'd either go with the LE3 or Ai next above setup.

Not that flow numbers mean everything, but the LE3's should flow about 280ish/192ish at .600

I just bought my 2nd set

If you go AFR go 195 at least

engineermike

Actually, if you go AFR, go 210 at least. Anything below 200 cc from AFR doesn't flow what they're advertised to. The 210 and up stuff flows really well, though, within 5 cfm of advertised. And NO, you won't lose any low-end.

Ill lose my wallet and my Daily driver witha 210cc head like AFR.

What!? Why?

Guys all the camps here have different theories as to why they do what they do with port volume, so don't always judge the heads on that. Lloyd preffers a larger port to get the velocity in the port slowed down in some areas where it can be a problem and the cams he uses are matched to that. Usually that means you can run a smaller cam to make more power, drive better and the head will like N2O more since N2O displaces air and fuel to get down the port.

Another thing is unless you measure the port volume and centerline length of the ports you can't compare them. Also there are critical areas of the port where the cross sectional area the porter will concentrate on setting that at a certain size. To get them smaller means you have to spend more time maximizing the velocity profile of the port.

Dont think you'd go wrong with either one.

You can definitely go wrong with the AFR 180's. As much of a proponent I am for AFR heads, the 180/190/195 will only flow 230 - 240 cfm.

I would go with AI. They are great and are the nicest guys to deal with. Their knowledge is unsurpassed. When I got my heads and e-mailed them, the e-mailed me back and they're last sentence was "Be careful". Go with AI they are the best!!!

I would go with the LE3's.

You will not be dissapointed with them.



There is a very heated debate on camaroz28.com about LE and AI. Search for it and you will find some interesting info. After about the 11th page, I got tired of reading what was going back and forth. (did not mean to add to any conflict).

There is little to no info on that thread, it is Bret and Joe going at it.

AI does great work. I would recomend them any day. I havent had anything done by Lloyd but i have heard great things about him. You will be good what ever you do. I wouldnt recomend just getting AFR's they will not flow as good as ported stock heads. But if you have the money buy a pair of AFR's and send them to Lloyd or AI and have them port them then you have a great pair of heads.

Do you have a link? I searched and couldn't find it, but thought I had seen it earlier today.

You know ,you would think sometimes Bret ports heads....
