Hi everyone, I need your feed back on a pair of AFR 210's that I just got back from porting.

Please see the pics here: http://jody.dltechnologies.com/afr%20210s/afr.htm. The images are huge because I wanted to show the details.

Please let me know what you think.

At this time I will NOT say who did the porting until I have heard back.

Thanks,

Jody J.


*** EDIT: I made a mistake!!! The spark plug holes on the outer chambers was do to AFR's casting and NOT by the porter. See the website ***

I have updated the site to include the before and after pictures

 

Holy ****, they sent the heads back with a hole in the port???

 

Wow. I hope you didn't pay for that.

I wouldn't be worried about the hole. It looks scary or whatever, but in reality you will have a bolt in there. You won't have a leak or anything.

If it worries you that much, I would just throw some high temp epoxy in there. and sand it down.

I don't like the fact that the head isn't deburred. All of the edges are still sharp or even knicked in some places. When my Ai heads came back they had the edges cleaned up.

Doesn't look like any real porting or functionality issues though. Mostly just cosmetic issues.

Was this a supporting vendor?

 

It just looks like a hole from the valve cover bolts (perimeter style) The other hole is a rocker stud hole.

There aren't any good pictures of the port or bowl so its tough to tell how much work has been done to them.

 

I'd be really curious about the flow/velocity, etc.---especially in light of the fact that the porter gouged a hole into the screw hole. Makes you wonder about the quality.JMHO

 

From what i have seen and heard from porters, its not uncommon to have holes like that in the heads when you get them back from the porter. Apparently you use some kind of sealant on the bolts when you button everything up and they work just fine. Its just part of the port reshaping process and any core shift in the casting and the porter might break through a bit.

As far as deburring, are you taking about the chambers? Would you recommend having a shop tig weld the hole and then re-smooth it out?


Yes, the small hole is the perimeter style, I didn't see the rocker stud hole. I guess I must of been to bummed to see it after seein the smaller hole.

These were bare AFR heads, so yes it was extensively ported. i'll get before and after pics of the heads.


I should be getting an e-mail shortly with the flow numbers, so we'll see. Your right about the quality, but the porter was recommened by a lot of people on the board


I'm just wondering what will it do to it's resell value.

 

I was talking about the chambers and some of the other edges to the heads not being deburred. It is done to keep from snagging gaskets or developing stress cracks (from what I was told). I just prefer smooth edges so I don't cut my hands up installing them.

As for the holes, I wouldn't be too worried about them. My Ai heads had a couple of places where the rocker studs came through. I left them as they came from the porter.

You have to keep in mind that the heads were flowed with these holes in the ports...if they were really hurting anything, it would have showed up when flowed. If they bother you, having them welded or sealed with epoxy won't hurt and shouldn't be too hard. A lot of extreme race heads/competition heads have this work done.

Looking at the head gasket surface, you might have that cleaned up or decked a tiny bit. Not sure if the marks are dirt or what, but even they shouldn't affect gasket sealing.

PS: If you're the same Jody from Irvine, the th400/driveshaft/suspension in my car came out of your car. I bought it from Aram who got it from you. As a heads up, Mike's Transmission might have screwed you, the internals were rebuilt stock level pieces. I thought it was built, as did Aram (because of the sticker on the side from the builder), but it couldn't even hold my power level NA. I had to have it rebuilt. Just telling you for future reference if you get a trans built there, that the internals might not be what is claimed.

 

I had a hole in my heads when they came back from porting. It freaked me out at first, but my friend told me to relax and applied some high temp epoxy to fill the hole.

BTW my name is Jody too.

 

Funny thing is I just wanted them ported because these were going on a 355 with a p-1sc and street driven. So what ever the porter did was his decision.

From the e-mail I got, the heads were milled to clean them up, but I guess I'll have to take it to a local shop to mill them some more.

Yes, I am the one that sold the trans to Aram. I'm sorry to hear about that, my old engine builder was the one in contact with Mike's transmission to build it. I gave Aram the receipt/paperwork so what ever work was done or replaced was on it. Again, I'm sorry about the trans.

 

Thanks for everyones replies. What do you guys think about the spark plug area on the two outer cambers.

 

It's not a problem. Live and learn...then upgrade. We were all just a little surprised to find out it was stock. Aram's car was nearly stock when he had the 400 in it, so he didn't notice. My car blew right through it. Just wanted to give you a heads up incase you went through them again.

Spark plug area looks rougher than normal, but still shouldn't be a problem. You could get some finishing touches done to them, but it won't change anything performance wise. In the bowl your main concern tends to be hot spots (especially on a blower car), so clean up would help prevent them.

If you don't mind my asking, what did you pay for the portwork? Just curious how much it cost as AFR210s have a ton of meat to be removed to get a finished product.

 

there are a bunch of ls1 that have that problem with the rocker stud threads which would sometimes cause an oil consumption problem.. to fix it just put some sealant in there. its not a issue..
