Everyone knows how good the AFR heads are, and for the money they should be. I am considering Trickflow's LT1 heads as they are considerably less expensive. I have asked my local speedshop distributor about
Trickflow, and he says he does not recommend them as they use cheap parts. How about that. Anyone using Trickflow heads, happy/unhappy with them??




95 Z28 LT1 A4 Red w/Black Ttop, 3:83, 52mm Holley TB, all the bypasses and relocations, full race suspension, B&B Triflow Perfomance exhaust system,et.etc....too much too list.

 

IMO and observation AFR IS NOT as good as everyone believes they are. They are living off their old reputation genuinely earned when OEMs had crappy heads and they made something better.. By the time of the LT1 OEMs stepped up in a pretty big way and AFR has not kept pace. They offer some products that can be useful to a few but not to the average person. The Trickflows are consistently getting good reviews from those tha use them, and the fastest LT1 b-body the forums know of is a Combination Motorsports creation wearing Trickflows.

 

You can't go wrong with either. AFR has a very long backorder, so Trickflow is the easy way.

 

Translation: "I can't make any money selling you a set of them."

 

haha yeah good translation

 

Your distributor is an idiot or a liar. Trick-Flow uses Ferrea valves are they crap?
I have never had a problem with a set of trickflow heads.

 

I'm kind of curious about the redesigned afr lt1 heads vs trickflow lt1 heads. I plan on getting a set of aftermarket castings this summer. I am waiting until I hear some flow numbers from an unbiased sourse (on the afr heads) before I make up my mind. Either set will be ported by Lloyd. I talked to afr they said the heads should be for sale in the next month or two.

The big issue with TFS heads is that they will offer a signifigant drop in compression, but if you mill the heads that will compensate for it.

 

If you are doing a stroker, and you are going to have them ported. Do flat top pistons and a set of TFS heads. I'm much happier with them compared to the standard 195-210-220 AFR's. If you need more than that, something like the AFR 227 or 215RR you could just as easliy go to a SBC casting and have it converted.

Maybe that will convince some of the blind AFR lovers.

 

I've never really been impressed by the afr stuff... Although some people have gone really fast w/ them.. Just feel there is so much more stuff on the GEN 1 side of the SBC to make it worth the 300 bux in conversion cost's..

 

Is 300 about what it costs??? If that is about right I may think about going that route

yea from what i've seen that's the avg depending on the quality of the casting....

 

I flowed my AFR 210 Race Readys on a Superflow SF-1020 with a 4.030" bore and got 280 cfm intake and 218 cfm exhaust. We've seen even better numbers from the 220's, Competition Package porting, etc. . . The Trick Flows (nor any stock head short of LS7) will not do anywhere near that. HOWEVER, we got no-so-good results from the 195 cc and smaller AFR heads. If you want something smaller than 210 cc's, get the Trick Flows.

The fact of the matter is there's only so much flow you can get out of a 23 deg head with standard port and pushrod locations. The 210 Competition Ported heads are just about as good as you can do with those limitations.

Buddy of mine payed for the comp. port 195s and they were junk. had to have them reworked quite a bit... He ended up making 450rwhp or so.. on them... in the end...
