Default New "Vintage" Trick Flow heads

The time has come, and our new DHC 175 cylinder heads for small block Chevy are available for purchase! They are being assembled as we speak, and will be shipping by the end of the week!

Trick Flow's new DHC 175 cylinder heads give small block Chevy enthusiasts a new performance option. No longer will anyone have to choose between vintage looks or modern cylinder head power, with DHC 175 heads you get both!

DHC 175 heads are made from premium grade A356-T61 aluminum and have the exterior styling and straight spark plug holes that deliver the nostalgic appearance customers want. On the inside, 60cc CNC-profiled combustion chambers with blended bowl machining under the valves and small cross-section intake runners promote low-RPM torque increases and boost high-RPM horsepower! The runners are finished with Trick Flow's superior Fast As Cast process that precisely duplicates the runner profile and performance levels of fully CNC-ported heads without the added machining cost. In keeping with the vintage design, the heads are available with or without accessory bolt hole cast into them.

Not only that, 40 lbs. comes off the nose of the car! $740.97 ea. with .600 lift Hydraulic roller springs...with or without accessory bolt holes drilled. On a 350, 60cc chambers net 10.6:1 with your average 5cc flat top piston, .040 gasket, and .010 in the hole at tdc. This is fine for pump gas. A 327 will be 10:1.

I am assuming that the exhaust ports are at the "standard" height?

Intake valve size is 2.02?

And the head bolts will require washers.

What about those who might want to stay with a flat tappet cam (do you offer an assembled package with those lighter valve springs)? And if so, what are the max. valve lift for them?

These heads are the best thing going. Extremely accurate castings, great ports that line up with all the OE manifolding, and the modern combustion chamber nets more "mechanical octane", reducing detonation.
Paint them orange, and nobody'll know, unless you tell them....

No reason to dump money into old castings anymore, these should make a night and day difference just bolting them on.
Believe they are 2.02 intake 1.94 exh

Love to get my hands a on set and see what can be wrung from them with minimal work.

Well it's about time somebody made a modern "classic small block head".

Evidently not yet on their website catalog. All I found were angle plug heads:

Why wouldn't you price them out as a set. Who's going to buy just one?

I'm going to go out on a limb and guess it's because multiplying by 2 is not higher math?

Besides, installing these costs more than just the heads, so both multiplication and addition would be required to use them.

YMMV

I know it's marketing 101 but do they really think that pricing them out that way fools us into thinking it's cheaper?

Anybody stupid enough to be confused by such rabid scheming deserves to be taken.

FWIW, I dislike "package" marketing where I am required to buy 10 hotdog buns in a package to go with 8 hotdogs in a package. I'm all about the al a cart packaging where I get to choose how many of one item I want.

I wonder if it's possible to get them with a pyramid symbol on the ends instead of the double humps (to simulate a 57 FI [539] head)? If so, I'd buy a set yesterday for the SB400 in the 56!

Quantity: Sold individually.

Pretty clear to me.

Maybe if shoes were "sold individually" people would only buy one.

I wish shoes were individually sold. Many of us have different sized feet.

Yes sir. Valve size is 2.02. Head bolts will need washers. Standard intake and exhaust port heights. We have options for flat tappet 1.470 o.d. single springs (.540 max lift) or hydraulic roller 1.460 o.d. duals. (.600 max lift).

Sorry no pyramids for now, but I could get you a good deal on a die grinder

Is there a spec sheet with flow rates and runner sizes that is available for viewing?
