Trick flow 235 vs ls3 style heads Ok so I'm in the middle of my build and I'm starting to have Second thoughts about my head selection. I got the TF 235CNC ported heads and have been thinking I should have went with a LS3 style head for my Mast Motorsport 416ci motor.
What are your thoughts?
What are your thoughts? when i had my 418ci, i used the TFS 235 and it ran great. first i had a ported ls6 intake with a 90mm snout and a NW90 tb. then, i ported the snout to 92mm and put a NW92 tb. it ran very strong, and the bottom to midrange power was just ridiculous. 
so, i say keep them.
so, i say keep them. Have TEA open your heads up to the 245 specs ,with a nice turned down ls3 valve,along with the nitrous exhaust port and you'll be set.
Plenty of power to be made with a cathedral port still
See my time in my sig,especially the mph as the car needs work to keep the front end down !
You have more left in those heads, to where you dont need to go to a sqaure port design
Good Luck

I had the same dilemma. I had the TFS & LS3 heads and was wondering which set to run. I checked with several people including Brian Tooley and all said if you already have them run the TFS. The LS3 are a good inexpensive alternative but if you have the TFS they are a better head.

If you have a mast 416 motor, why wouldn't you gone with with there heads too? They have a head and cam combo all match up already. I'm in the middle of research to choose which head a cam package to go with for my 2012 ls3 and I'm leaning towards Mast... anyone out there with any other opinions
The trick ,IMO, is matching the camshaft to the flow curve of heads you have. Either one, Mast LS3 or cat head TFSs, will make all the HP/TQ you can stand IF the rest of the combo works well with the heads of choice.
Im an LS3 head fan, but if you have the TFSs, run them and you wont be disappointed .

I have the TFS 235's and with a 90/90 on a 441 in a full weight M6, 550/512 rear wheel on smaller cam trapped just over 130 mph in the quarter.
Unfortunately the motor is out now with other issues but it will be stronger.
