. i was looking at the trick flows, 195cc $850 are they worth it? or should i look for something better for the few extra bucks, trying to stay around 1200 and under if possible.
I know AFR is getting alot of hype but are they worth it?
the eng pulled great to 4500 or so but started to die off from there, pulled to 6 no prob
i want this thing to really pull from 3000 to 6000-6200
so should i look towards biger heads? 210-220?but i dotn want to totaly kill the bottom end,
what i would really like to hear are likes nd dislikes from ppl
thanks chris

We just put a set of Brodix Track 1's on a motor close to yours. It was running "Double Humps". Talk about a wake up! Motor turns up much easier and picked up 6 tenths to boot. That was just out of the box. We are now pulling them back off for a little port and polish work.

cerbz,

Check out the last issue and the two prior issues of Chevy High Performance mag. Jeff Smith has done a fantastic job of running head comparision tests on both big and small block heads. very extensive.

The only "gripe" I have is that he didn't test the Dart/Buick 10 degree, the small block splayed valve, big block type, and the SB2 heads. I figure that they cost tooo much, plus have to go on a dedicated engine due to differences in pistons and cams, etc... pdq67

I have been watching peoples pro's and con's about heads here.I plan on purchasing a set of trick heads in the 180-190cc intake port range.It seems there is a lot of people displeased with Trick Flows because of mechanical problems.Do a search.There is a lot of people here who love there AFR'S ,I might be joining them.A few people here seem to like Cantons,and Performer RPM's too.Haven't herd much of Brodex,or the new Iron Eagles(180-190cc port).

I was thinking of purchasing the 190 AFR's for a mild 9.0:1 SBC. Can anyone provide their experiences?? What cam did you us for this setup? The AFR webiste rec's the Comp Magnum 270.

The cam on their example(Comp Cams 262XE)should be comsiderd as small as you should run with those heads as they have a 190cc intake runner.

I personally do not like the Trick Flows, they need some special rolelr rockers and just don't work great. For the same money the Sportsman II's or Dart Iron Eagles flow better and will make more power, (thier just heavier). The AFR's flow excellent as well as the Brodix heads. My buddy's 6-71 blown 355 picked up 1/2 sec when he switched from the Sportsman II's to the AFR 220cc heads. The AFR 190's are a nice street car head, but the iron heads will still really wake up an engine over the old 461 heads.

I`d like to say thnx to the few that have anwserd some of my question`s,

Bob tilley the trick flows need special rockers? self aline like the vortechs? or what?, I really dont like the trick flows to much my self, but there still in the back of my mind, trying to find all the pros and cons, af the heads out there, I know the mags have been doig alot on the heas lately, but you going to think there going to say a head os crap if they put a big add in there mag.? I dont think so

takeing my time, looking about BUT DAM IT I WANT MY CAR BACK!!!!!

I don't understand the roller rocker comment. Car Craft recently did an article as have others who say they are great out of the box and a good value/dollar. My short list has Edelbrock RPM, Holley, AFR and Trick Flow. I really like the AFR's but I'm not sure if the extra $ is going to make a difference on the street. Does anyone offer AFR other than factory direct at a better price?

I have a set of TrickFlows on the 350 in my 69 and haven't had any problems at all with them. I've installed guideplates, new chrome moly push rods, studs and roller rockers. Running a Edelbrock RPM manifold and 600cfm carb on top with headers on the bottom. Really woke up my small block.

Have run ported and polished 292 turbo heads
on mild bracket car. Went to AFR 220 and thought I was born again hard. 3260# camaro
with 372" went from 7.17 1/8 mile et to
a 6.55 et with the AFR 220. I priced alot of heads, I found you get your moneys worth with AFR.

(1) Does Summit own Trick flow heads now???

(2) Are the "twisted valve" heads still being sold???

Seems that I read that they had trouble with the moved valves guides and quit selling them.. Whats the scoop??? pdq67

Without a doubt the AFR heads are tops. The TF Twisted wedge heads are still being sold; the flow/performance is right up there. A few years ago,CarCraft took a pair out of the box, put them on a 406 with 236/244 cam and got 485hp/474ftlbs! The TF 23 degree heads flow as well as anything in their price range. Sportsmans have a good intake port but the exhaust needs help; Iron Eagles are better for same $. Anyone know anything about the Iron Lightning heads avail thru AFR for 800 complete?
