Trick Flow 240 Porting posibilities

[m79ded]

Hi
I just got a nice set of Trick flows and I am debating weather to smoothen out the small ribs left over from the CNC porting. I was told to just smoothen/remove those ribs by some people, some said do not touch it because those ribs help some said do not open the port any more you will ruin the head. I would like to ask our community here before I touch them and ruin a set of heads. I know guys like IQ52 or Dwayne Porter and other very knowledgeable engine builders on the forum might have experience with those heads and chime in.
It's going on a 451 that will be about 10.75 comp and a hydraulic 236/242 cam
Thanks

If you want more out of your 240’s, sell them for the larger Trick Flow head. It’s just a hell of a lot easier.

post pics of your trying to accomplish, but I would talk to trickflow first, also mite be worth having it professionally done so that you know your flow numbers, plus with your cam you mite not even need more airflow.

What are your goals for this engine, HP & ET. Jim did my 440+6 with 240 trick flows OOTB 9.9pistons nearly identical duration as yours and got 590 HP.

Good idea I will call trickflow before touching them.

My opinion, with that cam you don’t need to do anything to the ports.

BTW mine was a solid roller cam with 1.6 HS rockers .620ish lift. The thread is "Trickflows on the 440"
Jim did a little port work on the intake as there was more to gain there than the heads.

^^This pretty much sums it up. That cam is your cork, not the heads.

Just in general: which modifications would net the biggest gains on the TFs? Clearly some modifications require more work than others.

I would defer to Jim, IQ52 or maybe Mike, Hemmirunner. But my thinking is until you have a cam, carb, & intake that are not the restriction I wouldn't touch the heads. The restriction on my combo is probably the carbs, intake, then cam in that order. Doesn't matter if you have a 3" firehose if it's hooked up to the house 3/4 spigot.

The 240’s flow some impressive numbers out of the box, 270’s even more so

 

[Hemirunner]

Jim is the guy on this one for porting advise but I can tell you that unless you’re a real good head porter, the last thing I’d do is put a die grinder in those ports. You should probably be looking at the overall combo and what the goals are for this engine.

To think that nothing could be gained by proper work on the Trick Flow 240 is pretty funny. I have ported 906 factory iron heads in the shop that flow more than the OOTB 240's. But remember, AndyF has made more than 700HP with OOTB 240 heads. Until you are a better engine builder than Andy, well, whatcha gonna do?

Huh, I had forgotten what a flat torque curve(?) that engine put out.

I'm not arguing that I'm anywhere as knowledgeable as Andy or you Jim - I just want to know what the potential is of the 240s and which mods get the biggest returns.

I didn't think you were attempting to claim any such thing.

A well ported 240 should go into the 370+ cfm range just like the Indy EZ. With those cfm's we have managed 840+ HP

Then you see, the thing is, I don't teach porting.

People have asked for pictures of our ported Indy LAX heads (629 HP), 906 heads (748 HP) and Edelbrock RPM heads (789 HP). Ain't never going to happen.

People have said, "You're supposed to share your knowledge here on the forum Jimmy! You're supposed to share!"

So I do.......up to a self-determined point. I guess that makes me a bad boy. I don't care.

Shame on you for not giving everyone your secrets!

I didn’t say you couldn’t improve upon them, I said (or at least meant) unless you know what you’re doing you could screw up an otherwise well done cnc port.
