Ordered thru Jegs on July with promise to August beased on a factory order they had since February. Then they (AFR) said to drop ship last week. Today they say date is Oct 31st. I guess by then I better see a real witch with Santa than these heads.
I wanted the AFR180s for better low speed flow on a 350 TPI (Edel base, AS&R runners, fully ported plenum, XFI cam). What else flows as good or very close to these AFR? I havet he $$ burning in my pocket TIA

 

Dart Pro 1 180 heads seem to flow close and probably as good if not better with just minor cleanup.

This is from Super Chevy mag.
200 134 114 85%
.300 187 145 78%
.400 231 164 71%
.500 257 172 67%
.600 261 174 67%
.700 264 175

head with a ratio of over 90 percent, although rare, is capable of extremely good power numbers so keep an eye out for it. Check out the very high 85-percent I/E flow at .200-lift of the Dart Pro 180. This is an area of critical performance for any head, but particularly a street head that won't be run with much lift. Since the valve will see this area twice during every cycle, once on the way up and then again on the way down--as opposed to seeing max lift only once in every cycle--low-lift flow figures are often overlooked, but very critical to making the best power.

 

trickflows are supposed to be pretty good.

 

TrickFlow has 195cc and 175cc runner heads. I would get the 195cc heads if it were me. Check out Summit Racing - High Performance Car and Truck Parts | 800-230-3030 for your heads.

 

get some dart 200cc or trick flows that are comparable. i really like the new dart iron eagle platinums, or if you want aluminum just flip through the summit website for your varous choices. remember iron heads make the same amount of power as aluminum, just the weight savings isn't there.

 

195cc TrickFlows get my vote.

 

Thanks all for the replies. Would I see a big difference between the CNC and non CNC Trickflows?

 

Possibly... how much power are you planning to make?

 

glad i found this thread, i placed my order from jegs back in june, and they have been pushing the date further away every day, started out as july 26th, and now the dates all the way up to december 6th. i made a thread about this go check it out

CHECK THIS ONE OUT TOO

I have trickflows and am supposed to be making around 500HP. I got the CNC'ed ones. They look great when the motor is getting assembled. I think I got a pic...

Well I do, but not of the CNC job. Oh well. They fit/look great. I wish I had dyno #s.

Guess I will have some #s in the spring.

 

Take a look at the Brodix RR180 heads. I am running the RR200's on my 406 and the motor runs great. I do not have track times or dyno numbers but I do know that they fow better than the Brodix web sight lists. I flowed them at a local shop when I got them (don't always trust the manufacturer).

If you go the Brodix route, get the cnc chamber. I believe Summit sells these for a good price.

A truly undiscovered head.

You got me looking man. I think this is a new head (180cc) from them. The PN# BRO-1011001 at Summit has CNC int/exh runners and CNC chambers just like the AFR. The TrickFlows CNC heads TFS-30400006-CNC only have CNC chambers. Price is similar among all ($1300+). And these are in stock Let me see if I can find the flow#s. I just need a good set of heads to finish my build. If I loose 5-10hp to the AFR who cares. I like the CNC treatment on any head so that's a buy factor for me. Thanks again guys

 

FWIW - The flow numbers that Brodix lists on the exhaust side look somewhat weak. When I had these flowed, the exhaust side flowed much more than what Brodix listed. Intakes were on the money. When I talked to the Brodix tech, he said they flow all of their heads without a pipe on the exhaust. I had mine flowed with a 1 3/4" pipe. Same size as my headers.

 

Ja! Never mind guys. Called AD Performance and was able to buy his last set of the new AFR 180s Eliminator!!! Damn am I happy

 

Good now you can get them independtly flowed and see if they are all the hype.
