I'm thinking of ditching these heads for something better or I guess haveing these done up somemore. Some people tell me the afr 190's are great, others tell me theyre crap and arent going to get me into the 400rwhp range without spray. What do you think?

 

Get a bigger head,one that will flow in the 300-325CFM range and not tested on AFR's bench 'cause their's is very happy.

 

Which head do you recomend or see people making good power with? I'm leaning toward the LE3's but I theyed have to port match them to my intake I guess.

 

Good choice.Yes ya should have your intake matched.
There is a guy down here that has a set of AFR's on the board for sale,they are suppose to flow 301CFM.

 

What do the 190's supposly flow and how much is he selling his for?

 

Don't know,go look in the for sale section.His supposidly flow 301CFM.

 

We've tested a couple sets of AFR 190's at Thunder Racing and found 230 - 240 cfm peak versus 260+ cfm advertised. However, the 210 and bigger stuff all seems to flow within 5 cfm of advertised. My 210 RR's flowed 280 cfm peak versus 285 advertised.

I've been told that AFR uses a 4.125" bore fixture to get their flow numbers, which can account for 5 cfm difference, but not the 20+ cfm difference on the 190's.

I emailed the guy that does the LE ports. He said he could port my heads and get me in the 400rwhp range so I'm going to let him do the work soon.

 

I'm sure this will draw alot of flames, but keep in mind that LE's flowbench is optimistic when compared to some local benches (Thunder Racing, Larry Meaux, etc.).

 

It's all good. I dont know much about flow benches but I do know from searches that he seems to know how to make power without breaking the bank and I'm always down for that.
