this might sound like a real stupid question but hear it goes. i hear people talkin bout these heads all the time, but to be honest i have no idea who makes them??? a little help here... thax allot

 

AFR= Air Flow Research
They make many different style heads and have a good rep for excellent power making.They also use about 9 lbs. more aluminum in their castings which helps promote a better seal for the head gaskets,as compared to stock alloy heads.
I have their catalog and their prices were pretty good.
Seems to be a popular favorite on the sbc 350 crowds that stroke to 383's and use Mini rams or Super rams.

 

Oh...heres the link:

thanks allot for the info and link. hears what i'm planing the afr195 74cc competition heads a comp cams 306 cams with comp cams matchin 1.6 rockers right now it will be fed by a slightly moded 92 tpi system. i know this is not enough to feed the heads and cam but soon down the road is a full Holley stealth ram set up includin their 950 ecm. but will the car be ok in the time being wit the tpi??? also what else will i need wit this system ie msd, fuel pump, etc??? any input from anyone will be greatly apperacted
thanks:hail: :hail:

 

You have to be careful when ordering AFR heads. Their 195 is not an emissions head or has some other problem, I cant remember exactly what the problem is. I ordered their 190cc heads which bolted right up with all the right ports and EGR stuff.

I'm planning on having my AFR heads sent out for a little more porting work IF I ever biuld my stroker motor.

I think that the AFR heads are the best there is, period.

:hail:

 

i'm not worried about emissions since i allready have all of my AIR stuff off and a true dual exaust w/o cats but does anyone know of these problems wit the AFR 195's. and also whats the difference between the 195's and 190's?

 

Well, the obvious difference is the port size 195 vs 190.

Check their web site for why I did not order the 195, GM High Tech mag which is doing a 395 cu in called Magnum TPI, went with the 190cc heads, but then paid more to have them ported more out to 195, BUT they are not the AFR 195 heads, they started as 190cc heads.

The problem may have something to do with the cross over in the middle of the head, like I said, I cant remember the exact nature of the problem.

 

I have my AFR catalog right in front of me, the 190's flow almost identical to the 195's. I always thought the difference was the size of the port on the intake face of the heads. FEL-PRO #1205 vs. a FEL-PRO #1256. They quote the difference in size as being 1.280" X 2.090" for the 195's vs. 1.230" X 1.990" for the 190's. Not much of a difference, I would buy the 190's if building something emission's legal. I have the 195's because I got a killer deal on them, my father purchased them for a blown 355 he was buliding. He ended up selling the blower and I traded him a set of mildly warmed over Vette L98 heads & $400 for the NIB 195's. The heads I traded him had smaller combustion chambers and worked better w/ his N/A 355. Either way - you'll end up with a great set of heads weather they be the 190's or 195's.

 

AFR = best heads available....like he said, u cant go wrong

 

You may have header clearence to plug issues as I had with a previous motor.AFR use oddball size plugs.They are much longer than the stock plugs on stock tpi motors.So you dont have a choice in regars of getting a shorter plug.My slp headers hit on on of the plugs and I had the 195s with angle plug.Dont know about the straight plug.Heads that take the smaller type factory plug are a plus and eliminate this small headache.

 

Could just be your SLP headers, I have Hooker LT's and run regular Delco plugs w/o a hitch.

 

Brian what about the AFR L98 angle plug head? Does it have a different plug location than the regular AFRs?

 

Mike, with the exception of the AFR 227's - I believe the 180's, 190's, & 195's are all based off the same casting. The 210's are very similar too. Why would they retool? I'm not a fan of shorty headers at all. My LT's may give up some ground clearance, but I can reach 7 out of 8 plugs damn easy, like as if it was an older car w/o strut towers.

 

I believe the 195 are made for an edelbrock manifold. you would be fine with the 190's.

 

So is the only difference that the L98-style head has is the heat riser passage?

 

I have a set of AFR 195's with angle plugs and the SLP 1-3/4" headers.....no problems with the following conditions. I use the Bosch platinum version of the plug....which are the same as the vette L98 plug. And before anyone writes a diatribe in here about why i'm using the bosch's, its simple....these are the shortest non-lawnmower plug I could find AND they have a removable tip which allows you to shorten them another 1/8 inch or so. I did this to provide as much space as I could for the plug boots on a couple of the cylinders. Access is also easy for all plugs.

 

Wow
It's all about accessabilty. Makes sence to me.

 

No. It'll run like $hit, if at all.

You ever hear a car with a Comp 306 cam? Choppy as hell. That itself will play havoc with a TPI, especially SD. Also, the LTR nature of the stock TPI promotes low and mid range torque, while the 306 cam is made for mid and hi range. If you're really wanting to keep the long-tube runner intake, I would recommend nothing more than a cc305 with a mild stall converter, like 2000 or 2250. Similar pattern to an LT4 hot cam, costs more, but has a tighter LSA (114) for better use with forced induction, if you ever go that way. Also idles slightly better. LT4 hotcam is cheaper, has a 112 LSA, but slightly less duration for N/A motors. If you plan on using a shorter intake and having some prom work done, or using that HSR, then rock on with the 306 cam! :rockon:

You may consider locating a used LT4 hotcam to use with your car until you get ready for that intake, then swap to the 306.

 

dhirocz thank u so much that was the reply i was really lookin for what do u think about the afr 195's though good or bad choice, figuring i would be goin wit the cc 306 and the HSR?

 

The AFR 195cc is a great choice for your planned mods, but you might as well go with the smaller intake runner 190cc instead. I think you can order the L98 Angle plug without the heat riser. You should order the L98 Angle plug if you have SLP headers. I learned the hard way and ruined my SLP headers because i ordered the regular angle plug version. You could drive the car with a CC306 and the AFR heads, but with the long tube runner setup, it will be fairly dissappointing to you. The cam makes power where the tpi dies off which pretty much defeats the purpose, but if you are going to get the stealth ram, than it should be alright with the Stealth Ram. Keep in mind tuning is key in this setup as with any setup. You can have the greatest combination of parts but if tuning is way off, you'll still have a dog.
