Hi all,
I am trying to decide on Victor or Trick flow heads.
The engine is a 500" 440 based engine with 11.5:1 compression. I have a solid roller cam forget the specs right now. I have a Super Victor intake and a 1050 Dominator. Crank trigger with a 7al ignition. The converter is an 8" 5500 in a 727. The rear is a Dana with 4:30 gears. The car is strip only and weighs 2800 with driver. Not sure which heads to look at. So I am putting this out to get opinions. I know the compression is down a bit but the engine was going to be used as a street strip thing when originally built.

Thanks, Digger73 (Mike)

For that combo, I would go with the trick flow heads.

Why the Trick Flow? I am so up in the air that I am just fishing for information at this point. The season is getting closer and I want to get this settled so I can race...

Thanks,

If you want a simple to build race engine then get the Trick Flow heads. If you want some pain and suffering then go with the Victor heads.

Thanks for the input Andy.
I forgot to put in the original post that I am now set up for standard 440 ports. Is the choice still for the Trick Flows?

Thanks,

If you want the car to go as fast as possible go with the biggest port size heads you can get like the Trick Flow 270 or the Indy SR M.W. or 440-1 with the best intake to match the head port size
I have a set of Victor M.W. heads on my bracket motor, I'm not impress with them
The next motor for that car has a set of CNC ported big valve 440-1 with a Jesel paired shaft rocker arms on them
How fast do you want to go and how soon?
Don't forget that the head combustion chamber size and head gaskets used affect the true compression ratio

Might depend on the cam size? The Trick Flow 270 heads best offered valve spring package says 0.700" max lift? I'm not sure what rocker arms they use or recommend, probably a good question for Andy F.
The price is not too bad considering the heads are assembled with all the valve spring parts.

The Victors Max Wedge don't come assembled, and out of the box don't flow as much as the Trick Flow heads. Ported they do flow more, close to 400 cfm. Check the Hughes CNC ported version. They will end up costing alot more once you get into setting up the valve spring package and rocker arms. That extra 50 cfm is likely to end up costing at least $1,000+ over the cost of the Trick Flow heads.

Thanks all for the comments and suggestions. I found the cam information.
Comp Cams 315R grind duration @.050 Int. 280. Exh. 284. Lobe lift Int. .420 Exh. .401. I have 1.5 Crane Gold roller rockers. The head gasket compressed height is .051". They are Fel-pro black. The compression ratio was calculated using these head gaskets and Stealth heads. I know the Stealth heads are not the best but they are what I could afford at the time. I am now stepping up to a better head package so that is why the post. If it helps the Stealth heads have been worked over pretty good they flow 292 @.600 lift on the intake.

Thanks,

I just gotta ask why does nobody like or recommend the B1BS head? Hope I am not asking in the wrong place.

Std port Victors, when properly modified work very well....... But they are pretty far down the "bang for the buck" list.

Much higher up that particular list, while staying with the Victor theme would be the std port CNC ported Pro Comp head.
Buy them bare, have the valve job redone, install quality parts..... And you'd be good to go.

However, if you really want to wake up that 500" motor, especially for drag use only......... just step away from the std port heads.

Get the TF 270's and a MW manifold to go with them.

Compared to what else is available now, they just aren't very high on the bang for the buck list anymore.
They have a few quirks that some other choices don't........ And IMO, they don't do anything "better" than other current choices.

That, along with them being about the worst for header fitment/spark plug access in a regular door car doesn't help the sales volume.

They can make good power and are well made......I just feel for whatever the application.....some other head would make a better option.

Standard port would be the Trick Flow 240 heads. Max Wedge is the Trick Flow 270 heads. If you have a standard port Super Victor then it could be opened up to a MW Super Victor without a huge amount of work or just sell it and buy a MW Super Victor. The MW setup would make more power in a race car, especially with a Dominator carb and a big cam. The 270 heads are also easier to work with since they overlap the valley plate for a good seal. The 240 heads require some "trickery" to get them to seal to a solid valley plate.

Trick Flow 270 heads right out of the box with a Super Victor intake, a big roller cam and a Dominator carb should make a solid 700 hp. It should be a bolt together setup.

Here is a comparison between the heads: http://www.hotrod.com/articles/dyno-day-trick-flow-270-mopar-heads/

I'll have this 470 with 270 heads back on the dyno next week testing some new valve springs. I'm shooting for 800 hp on pump gas so my compression is less than yours.

So if I am reading this right the 270 heads are the way for me to go. I will need to get new rocker arms and intake to make the swap. Would you recommend 1.6 over 1.5? As long as I am having to redo the manifold is there a better choice than the Super Victor?

Thanks,
Digger73 (Mike)

BTW, Andy would you like to buy your Super Victor std port back? LOL

What rocker arms do you have now? The 270 uses standard rocker arms so what you have might work.

The standard port SV will work with the Trick Flow heads but you'll give up a little power. If you're just sorting out a new combination then run your existing intake until you get the car sorted out and then put a MW intake on it. It isn't going to make a huge difference, maybe 30 hp or so.

Andy,

Thank you so much. This is great information. I was under the impression that I had to change the intake to a MW for the heads to work period.
I also thought that with the MW runners that the rockers had to be upgraded to offset intakes. You just made my decision that much easier. 270 Trick Flow here I come!

Thanks,
Digger73 (Mike)

Forgot to add, I have Crane gold roller 1.5 rockers now.

As was mentioned, the std port SV can be opened up to MW size.
No need to buy another manifold.

Read the 270 articles that I've written and study the pictures. You'll see that I used standard offset rocker arms on the 270 heads and that I've used a standard port intake on the 270 heads.

It might not be "ideal" but it can get you up and running and then you can upgrade from there.

We are all talking about the same thing, right?

A "Super Victor", #2891........ Not a "Victor" #2954.

From what I can gather, the 2893(MW size SV) is just a 2891 with the port openings CNC'd out to the MW size.

I think the Trick flow heads a are a good bang for the buck head. I like the 240 I got, but that is a mild street engine. For a 500"+ engine with a big cam, that is used for racing, the larger ports is what you want.

On the B1BS head question, The heads are a nice quality part, but are not as price competitive as most of the other heads.
For Example the basic unported (standard port opening) B1Bs head only flows 295 cfm and costs $1,069.84 bare, $1,354.03 with springs and steel retainers, and $1,465.40 with springs and Ti retainers. Price per each head.
The thing with the standard B1Bs is it has nice small 65cc chambers that help boost compression on stock engines, but it also can make compression too high in many performance or stroker builds.
The B1BS head also requires an offset intake rocker arm design adding cost to a head that unported flows about near same as an Edelbrock RPM or milidly ported Stealth head that do not require the offset rocker arms.

The STS CNC ported version of the B1BS flows 348 cfm, and costs $2,475.15 with springs and Ti retainers. That is the cost for one cylinder head.
It had been awhile since I looked into those heads, but I thought they are opened up to Max Wedge port size, and the chambers opened up too a larger 80 CC volume.

The CNC ported B1BS is actually more expensive than the B1 MO head that flows 396 cfm, and costs $2,032.58 with springs and Ti retainers.

I haven't look at the price of the Stage V hemi conversion heads in several years, but likely not much more than the STS CNC ported heads?

Roughly twice as much as a TF270 with comparable hardware, and it flows about the same...... but doesn't require the offset rockers or special headers.
