Small block TrickFlow heads part 1

Head/ports fixed from what I read.

I think you really can’t discuss one head without the others being brought up. My post above with the links is just a comparative note. 67autocross is having his PM heads flow tested.

For many here & even more so that most will not themselves port a head, the flow rates vs dollar spent is where it is at for them. Also, even though it has been said a hundred times a year that you just can not bolt on a big port flowing 300 and expect miracles still wonder what to do and how it can be done better. A plus without a big expense.

It’s also hard to get a low-ish duration cam with a lot of lift to take advantage of the high flowing head. (Enter in 1.6 rockers) While it is not completely necessary to do so and you can run quick without the extra lift, I find it pointless to get such heads and not lift the valve up high. A well done valve job and bowl porting can take you pretty far and fast if the rest of the car is up to the task. Most here have a heavy car and dream of big speeds and low ET’s.

IMO, the 2 heads above represent the best bang for the buck heads readily available for the small block Chrysler right now. 1 just a bit better for a price. Or the price.

I hear ya.
For me... this is the thread AFTER the initial inspection and weighing in of other heads. Like a quick run through with ootb pics and then ideas of where to go for improving them. He has yet to start any work on them and it would be a shame if like the other thread of his with seedblasters... that it ends up 4 pages of excellent walk through tech..BUT.. that you have to fish through 12 pages of other heads, head porters, bench differences, what ifs, when so n so...etc..to get to it.
Ideas are excellent, dont get me wrong. I just dont want to hear about other heads that aren't even the same animal in a way.imo lends nothing.
What's important..
Hes doing a baseline and providing steps and results with the head he has..the trickflow 190 sbm. So in reality..the end result can wait to be preferencly scrutinized or compared to the other heads at that point, if so. It's too early to know and way too easy to cloud it up if you start in with too much branching off. This head is unique to mopars in the ootb port volume and then the guide fin alone ootb. Chevys, ford, trick flow in general have had that around for many years and now you see it in one of our own versions. Consider the head bolt area and lack of typical crude bolt buldges... do you consider the union of those 2 features? There could be more than numbers... there could be flow gained and power lost, depending on the way the fuel and air mingles or doesn't, again depending..

Jmo. Yours may vary and that's no issue.
