Scott,

Send the heads back to AFR so I can flow them before you rework all of them.

Im fairly confident they will flow alot closer to what we advertise than the numbers you posted on the exhaust (intake flow was right there) but anything is possible.

If the heads dont flow close to what we claim we will cover all freight and make sure they do when we send them back. I know you can do your own work and are capable of handling the situation but I would like to see the results on our flow equipment.

Also, can you post a pic of the pipe you are flowing it with....I would like to see how it compares to what we use at AFR.

We are close and shipping is only a day or two each way.

Thanks,
Tony

Thanks for the offer Tony but there's just no time left on this project, otherwise I'd be happy to work with you on this. I'll get a pic of the pipe when I have a chance.
I hope you recognise this isn't meant to be a "bash AFR" thread. I really like these heads.

This post is very interesting! can you do a brodix rr 294 when you get a chance?
Im really looking into the AFR 305s and the Brodix 294s

My 335 AFR heads were all done at 380 cfm and 382 on the good port. This was done on a SF 600 flow bench with a 4.5" bore plate.

I'm sorry I posted in this thread.

If this turns into the usual flame war over this and that brand of head or porting shop it's history. Sooner rather than later.

does seem a little strange. posts up a negative comparo then blows off offered help? What's wrong with this picture?

I'm not "blowing off" offered help. Sorry it looks that way but there are scheduling issues that my customer isn't willing to work around. That part isn't really anyone's business but I thought I'd offer an explination.
I got a very nice call from AFR today offereing to fix the heads and even CNC the chambers for free. You can't ask for much better customer service than that. Unfortunately the timing isn't up to me. I'll have these done tonight, back on the bench tomorrow, and out the door the next day as per the customer's wishes. That puts them, me, and my customer about a week behind schedule as it is. It also puts me a good 8 hours into these heads that I don't get a dime for, but that's my customer service. My responsibility is to my customer, not AFR or anyone else here.

Tom. it's OK. I think you fell a little victim to 5325user's trying to instigate trouble. He's from another forum, was banned from Perf. Boats permenantly for doing nothing but the same, and a few other sites as well. He's just starting trouble and his main targets here are/will be me and Straub.
Just wait.
You'll see.
As far as this thread, I was hoping it wasn't seen as a bash AFR thread. It wasn'y meant to be, but I can see how it'll probably turn that direction, but not by me if it does.

My take on this was that the OP didn't have the time frame to accomodate AFR and the end user both so he took care of the issue at his own expense. Admirable and great customer service to boot. Kudos to Mamo for the offer to personally check and fix his product. Not sure if any other cyl head mfg rep/designer would even respond. It would be nice however to receive a product which was exactly what it is supposed to be. These days engine parts are not cheap by any stretch.

 

[Tom Mobley]

I'm just in total burnout on these head threads going south.

Scott, I'm sorry I questioned your integrity, stupid of me since I had no idea what your customers needs were. It won't happen again.

Tom, you are the bestest modfurcator eva. :beers:

 

[Camaro_fever68]

Did you get the heads fixed up? Shouldn't have took much? Couple swift marks with the grinder usually works.

I've been doing a couple heads and learning from one of the best that's not far from me. About to invest in my own SF600. Yet to master the valve job though. Never knew how important it was.

LOL..."couple swift marks with the grinder"?? :noway:

Update:
I finished the chambers on these last night and hopefully can get them on the bench today or tomorrow morning.
As far as AFR and them helping, well I have to say they've gone out of their way to help on this within the constraints of time. I received another call yesterday, this one from Tony with another offer for help that I did accept, and they even offered to make up for some of the lost time on these heads. Thanks Tony and Rick for your efforts here. You guys are outstanding.

I want to reiterate something...this thread wasn't really about AFR or Dart. Was I disappointed? Heck yes, but I could have used "BrandX and BrandY" to make the point, and that is; if you don't care about the flow characteristics of the head and are just looking for a basic performance upgrade like most are, that's fine, but if you're depending on the advertised flow numbers to meet a goal for a specific combination, like I was, you need to verify that you're getting what you need. One way to avoid this is to buy the CNC chamber option which the manufacturer has way more control over, instead of the as-cast versions which can vary considerably from head to head.
Again, thanks to AFR for their efforts here. It speaks volumes. :thumbsup:

Hey Scott, you fix that valve job and you would find your advertised flow.
