    Like Title states, I currentley run a pair of the trickflow twisted wedge heads part # tfs-51400004 they are the 170cc track heat heads with 61cc chamber, they are slightly hand ported and gasket matched to lower intake with ed curtis valve springs and a valve job.


    I was wondering whats the best cc heads on a all motor 306 c.i h/c/i full bolt on cars, I currentley run those heads with a ported trickflow track heat intake with 75mm tb full exaust long tubes, comp cams xe274hr extreme energy cam, It makes power all the way to the 6200rpm cut off, my ? is I was thinking of selling my trickflow heads to upgrade to a new set trickflow has out they have a pair of 185cc heads and 190cc heads guys seem to say they are a ton better? my ? is what cc head should I run my current compressions is 10 to 1 I want to keep it around the same so these are the 2 heads im thinking of buying to replace my heads with they have diff cc size so didnt know what was ideal for a n/a all motor 306 car.


    my current head is this below trickflow tw 170cc (track heat head version of this )

    I've read tests they show a 30-40 hp gain through out the power band esp on the top end for the 185-190cc heads over a 170cc head.

    What are you trying to accomplish? Just a little more power? Or just to change things up? I think the 170's are plenty for a 306 that only spins to 6200

    I'm pretty much done with my car dont want to spend money now but down the road I will prob change it up, maybe see if I can get more power or top end power, I might get a msd box or raise my rev limiter to 6500, see if I can get a little bit of more power and My cam and intake and everything else I changed, I still run the same trickflow heads, so down the road I can get like $800 for my heads or so, I want to put the money towards a better head, I just not sure what ccc and size, I think a 185cc head would be perfect? another memeber told me to run the heads below. Ive seen dyno where guys gained 25-40rwhp with the change in heads on a 306 or 331 motor.

    Get the 11R 190 Street ports.. They are $1569 shipped from Fordstrokers. 56CC. Already have LSX springs and 8mm valves.

    I have the trick flow 185's and they're a good looking head.. personally I wish I would have gotten the 205's but I think they would be to much for your motor.

    Jeff, tell us more about the pistons in your engine. We could give you a better idea of the comp ratio you'll get that way.

    If you're at 10:1 with 62cc heads, I'd stay in the 58cc - 62cc range. You can always have the heads shaved to bump the c/r up later.

    Brodix makes a good head as do Dart.

    Honestly I think You should just keep the 170's unless you have bigger plans for later More displacement or boost.
