I’m gonna order a set for a solid roller build I’m workin on. I’m only at 10:1 though. Don’t wanna go more than that really. More street than strip.

I’d put some compression in it and just turn the timing back on the street then bump it up with good gas at the strip

I just don't get it. 191cc, why?
Basically where all these stock config heads are coming in at, and it's just not enough.

The Air Wolf 220's have enough volume to support 600+ horse without big compression and without a big roller cam.
He's been out of business for years and no one has duplicated the effort...WTH?

Anyone that has talked to the TrickFlow guys will know they aren’t idiots. 80% or more of the Mopar guys building small blocks will be happy with these. I’m just hoping they offer a better head in the near future

I talked to Dwayne about these heads couple weeks ago.
He said a well done, zero deck flattop piston stroker with a good flat tappet cam will make 600 falling off a log with these heads if they are any good. And initial reports sound like they definately are good
I have no idea what else somebody could want out of a direct bolt on factory replacement head.
90% of small block guys would consider that stout. That is the class Trick flow is teaching to
The more exotic offset stuff most tight wallet Mopar guys are just are not going to buy in any numbers to make such a product viable.
These heads should get a typical bracket A body car in the 9’s without anything exotic. That accounts for most all of the market

Not to draw away from original poster's intentions, but... what I'd like to see is comparisons between Eddy vs Trick Flow. I'm building a 410 with CR about 9.5-10 (Hughes kit, engine partially built)... camshaft (flat hyd) still to be determined ...wanting wide range rpms especially strong mid-range and ability to run strong higher rpms (I do pylon AX, HSAX and road course lapping sessions).

My purchase is on-hold until ~mid-summer or end of this summer, maybe into early 2020... maybe the EDDYs are simply established and proven.

Edelbrock heads and TrickFlow heads shouldn’t even be mentioned in the same sentence. Edelbrock heads are poor quality and max out at 243 cfm. TrickFlow heads are nicely set up with several options, cnc ported and flow over 300 cfm with several options offered

^^^ Yep.

What heads have the HR springs on summit?

UPS just left a box from Summit....weights 61 lbs....

I'm about a month or some from ordering...pics...specs...rocker arm/ pushrod data...inquiring minds wanna know...

Took them out of the box....photos thats all

Are you going to get them flowed or just bolt and go?

We ran a 408 on the dyno today with a set of the Trick Flow heads. Engine had a Performer RPM intake, Holley Sniper setup and a 230/236 hyd roller cam. It made 450 hp and 490 torque. Not bad numbers for sweet street engine. It idled super smooth with a ton of vacuum and was a very quiet and smooth engine. Should make a great cruiser for the guy. This is the first set of these heads that I'd seen. They look like they'll make a bunch of power but this was a street engine rather than a race engine. Anybody else have some numbers to share yet?

Interesting question but it will take a while before anyone does that sort of test. You probably need to talk to Hughes Engines or maybe Brian at IMM to get some A to B comparisons. Not sure how many folks even have the SB Trick Flow heads on the dyno yet. The engine we ran today is the first set that I've seen.

Morning Andy, was this an LA or Magnum engine and what was the rpm operating range, thanks!

LA engine. Peak power was around 5200 rpm, I don't remember where the torque peak was. I was just there to help tune the Sniper setup and I didn't keep a copy of the dyno sheet. Should be a sweet engine in a street car. I think the customer had a Duster 340 that it was going in to.

Here are a couple pictures of the engine we were working with.

What size are the headers?

I think those are 1 3/4 Schoenfeld sprint car headers but I bought them a long time ago so I'm not positive.
