Trick Flow Twisted Wedge heads. I have an opportunity to buy a set of these heads. I know the rarity factor of these heads and the little bit of info I've read says these are good heads. The questions I have are what are they worth? and how do I easily tell them apart from a regular Trick Flow LT1 head? Any help is appreciated.
They are definitely good heads as cast, but ported they can provide some lethal gains when coupled with a cam/valvetrain to boot.
LT1 heads are easy to identify - there is no coolant passage on the front and rear of the heads.

Thanks for the info.
However, the thing I was wanting to know specifically is how to tell the twisted wedge heads from the normal trick flow 23 degree heads? Does anyone happen to know. I don't want to go buy them and then they turn out to be just regular trick flows that can be bought any where. They supposedly only made like 7 or 10 sets of the twisted wedge heads ever.

I have it on good authority that someone who used to use those went FASTER with the right ported GM LT1 heads and that those were hard to keep valvetrain alive in.
The ONLY reason I would look at them would be for the neat factor.

Hey:
Just know they need the backset r rockers that comp sells and intake and ex take different length pushrods, If not properly setup they are prone to break springs and wear guides. When set up with correct geometry and ported the LTX TFS TW last generation heads put out very good power thru a very wide range, and don't need to be revved to do it.
Had them on 1 of our C I limited WORLD OF OUTLAWS (WOO) Super Sprints, they work great on 355 engines. I don't know if TFS sells the special guide plates any more as well, they kinda of gave the Kenny D/TFS name a bad rep awhile ago, that they have since overcame and then some. Some size valves may be hard to locate for them and they do not make as much power as many new 18,21,& 23 heads, and were discontinued. Just make sure they are complete, with valves, guide plates, backset roller rockers, TFS valve covers, springs and so on as you will be on a Treasure Hunt if not to find the correct stuff.
