trick flow R heads

[86gt5.0]

hi i was lookin at the trick flow R series heads and they seem to be a great head with their 2.08 valves and what not, and i was wondering if they were
1) street legal i.e. passes emissions
2) too much of a head for a mild 302 build
3) worth the money
4) has anyone had any sort of experience with them

thanks
Jim

The are definetely worth the money for a 331 or 347. Not with a 302 though. Too much head.
Not a big deal though, if you have a 302, use track heats or wedges, and there are companies out there with good cnc programs for them, and you can upgrade when you need it.

The R's are too much head for a 302. Twisted Wedges/Track Heats are a great all around head. Out of the box they perform well on a 302, they have lots of porting material (so I'm told). Send them to TEA and they will work great on a 331/347/393/408 or boosted motor as well (if you ever decide to build something of the sorts). Another head that has a very broad range is the AFR 185s.

yea i thought the R's were too much of a head. but i wanted some reassurance on the issue. i think though i might just go wit a diff setup. but we shall c. one more question
will ported trick flow wedge heads
1) make more power than afr's( i heard they flow better)
2) will they pass emissions?
3) would they work well on a sd motor wit stock cam?


thanks again

1) If they've been ported by somebody who knows what they're doing (Fox Lake, TEA, etc) then they should out-flow out-of-the-box AFR 185 (especially on the intake side). Out-perform....all depends on the rest of the combo

2) I believe the Twisted Wedge heads have EGR provisions and the Track Heats do not.

3) Somebody else will have to take that one.

Don't take this the wrong way, but if you are using a stock cam, SD on a stock shortblock, looking ported anything is a waste of time.

I would go Maf, use a custom cam, TW's, and a good intake. If you plan on going with a 347 in the future and don't want to blow the money on a custom cam, you should be able to find something off the shelf that's decent.

i kno the stock stuff isnt the best but i was told that the 86 sd cam is actually a good cam, not the best by far but not bad. so i figured that if i got some great flowing heads on it that it might make good power. so that was just a stupid thought though.

to jason 5.0 the twisted wedge heads ported run wit afr185's? i thought they would still be wit the 165's? thats awesome i might just do it.

[Jason 5.0]

Yes the Twisted Wedge heads have great potential. If I were going to get a set I would look into these guys. 2000xp has had a set extrude honed he can probably chip in on those. I also know a local fella who had a set extrude honed for his 408 stroker, however has been building the engine for about 5 years now. lol

jason 5.0 thanks for the help man. i however have a guy who will port the heads and i kno he will do a great job, b/c of his clients. he works on half of nascars and nhra's heads and i kno he is the best. but i appreciate the info. one other thing i would like to kno will the heads still pass emissions after they are ported?

[2000xp8]

If he works on those types of things, he'll know when you tell him what you are doing, not to port them. Bowl cleanup and valve job, yes, but no porting is really necessary.
Porting them is going to kill velocity, and make the engine only run well at high rpm. And as a person with one of those types of engines, it runs really well, but is a bi*** to drive out of first gear. Car loves to be beat on, but that's about it. I can live with the sacrifice, but i have multiple vehicles, combo of my clutch and high rpm engine could make me crazy if i had to do it on a daily basis.
You seem to really want some type of ported head, but in your situation it makes no sense at all.

im only asking, and i would like to thank u all for the help. i have learned quite a bit.
i think for now i might just go wit my original setup

[2000xp8]

I don't know much about your original combo, but don't waste any money on less than par heads.
Use gt40x, edel rpm, anything tfs, afr.
I'd steer clear of the rest of them, Iron heads are money pits, sometimes with little power gain.
Go maf also, it can be done relatively cheap, and you may land up there regardless. This way you can get the cam you want now, instead of pulling your engine apart tice.

well i have a motor donor wit maf comp and motor for 300 dollars. but my original setup was to use a mock cobra motor wit either a trick flow 2 cam or a compcam 280hr. i was gonna hit the junkyard and c if i could get the heads and intake for cheap. i was just gonna use stock iron gt40 heads. they flow well from what i have read and are cheap.

[2000xp8]

Think of it this way, on a rwhp dyno, an auto explorer 2wd makes about 190rwhp, that's with gt40p heads, gt40 style intake, explorer 65mm TB. Crappy cam though. Mid to low 13's with an e cam (in a mustang). Nothing that can't be done without heads at all. That's why i don't like them.

^^^ so ur saying basically Heads before Cam
