What are the options of aftermarket heads and the best stock 440 heads?.

 

If I was starting from scratch I'd go with Trick Flows for a street strip motor.

 

I've heard they're coming out with a max wedge size head also.

 

You need to figure what the motor RPM and use will be first !! Street or race or combo
there are loads of options

Last year I spoke to Edelbrock and a number dealers (Mancini, Summit, JEGS, etc). They all came back with the same answer. If a proper porting job was done on the stock heads, going to aluminum won't buy you anything, except maybe looks. Remember, these are the guys SELLING the heads and they talked me out of it.

I don't know about the Trick Flow, or if you want to buy aluminum heads and THEN have them reported, which might help in a race situation.

If the stock heads are off or coming off the block, having a good machinist do a number on them might give you the most bang for the buck.

So it really comes down to what you're looking to do and your budget.

Here is bang for the buck!!! You cant do a set of stock heads for this!

Sold as a pair!

 

I have a set of blueprinted 84cc Edelbrock Performer RPM heads on my 500 stroker. I definitely recommend them

 

If aluminum,doesn't that open up on pump gas a SCR by one point?.

Question is are the 440's limited in how high they rev?. I recently looked at a 440 build that was a hydro roller.Seems like the HP ratings fell apart when they lower the SCR for emissions to 8.5.

 

Which stock model numbers to look for to have ported?.

 

Emissions?

 

Closed chamber 915 Open chamber 452/over 5.50 lift 906

 

Don't know if I agree, but I have a 500" 440 that has a pair of 915s that I have worked on every time the damn thing has been apart in the last 25 years ( three times) , 2.18s 1.81s lots of bowel work and port matched that's it. 645 hp.@6000 and 620tq.@4500. and still making 620 hp @ 6500.


Bob has seen the dyno sheet, I'd still go with the Trick Flows for a street/strip!
You will be $$$ ahead and 50 hp. ahead. The Trick Flows are fully CNC ported and use standard rocker setups.

2K ready to bolt on By the time you have someone rework them, new valves / springs /retainers and machine work you are talking probably the same money.. Aluminum heads can run a point more compression
PLUS the weight savings

But you're comparing heads that were basically ported at the factory to the Edlebrock heads I mentioned, that aren't and need more work to bring them up to "speed". The Trick Flow heads seem interesting, and might be worth looking into, but that still depends on the RPM the guy is living at. 50 HP at WOT is significant, but if the guy is living at 3000 90% (+) of the time, maybe not so much.

30 years ago, my car was a real street/strip car, these days pretty much all street. (Just aren't any "strips" withing driving distance.)

I think my heads work good for what they are but I've seen seen dyno sheets with the TFs and a cam I have used in the past. TF make better numbers everywhere especially in torque. I'm old school and don't go for the latest and greatest most of the time, but if I tripped over a pot of gold I would have a set.
