Pretty cool! I'd like to see some flow numbers.

Neat heads!

Me too, along with port volumes.

Certainly many 'fresh' ideas to apply to Pontiacs. Chambers look as up-to-date as any. And they appear to be well thought-out, for instance the cast-in bolt bosses for those who mill off the exhaust doglegs.
(Could we finally have an actual 'big block' Pontiac? We've all come to recognize Chev big-blocks by their canted valves, right? ha!ha!)

More like a Yates design. Yates intake($466.39)+(spacer $70) and 351 valve covers. RPM range 5-8K RPM.

Not sure where they get $2500 bare but $3000 finshed. I think I would want more than $500 in valve train and valve job to handle that kind of rpm. I think $2000 bare is a better starting place for a bare head. High ports are only $1500, FWIW.

Overall it looks like good design and a product I would consider buying once all the parts that go along are available, not the stop gap stuff. Thanks

Divorce the center exhaust ports and we'd be there.

[Larry Navarro]

Wow!
$3000 for complete heads! Not bad for a completely redesigned head.

[Ron H]

Very impressive. Wow. Can't wait to see some numbers from that set up.

[BILTIT]

Very interesting, need some new heads in the next few years. The more options the better!

[R 70 Judge]

I wonder if they could add a few extra head bolts?

If these things make major power and I can get a whole new top end for less than 4K I'm going to seriously consider buying a set.

It's worth it just to be different.

The intake looks like a ford SVO unit, lol.

Ventura7211, What would you know about a Ford SVO anything? (couldn't resist a little friendly comment).

I know the intakes work alot better when you cut them into quarters, port, then alter a couple runner lengths. We still ran into problems with the back two ports number 4 and 8 needing 1-2 larger jet sizes in the fuel side of the fogger.

Yes, it looks like a ford intake, because that is what it is modeled off of. Doesn't really matter who "made" the intake design, what matters is now the pushrod bulge is gone, the intake runners are now canted with the valve, there is a whole lot of improvements done here. I like the idea of being able to cut off the exhaust runners for a really short runner Not that I will do it for my TA, but it's cool that it was designed into it.

Its not a bad thing that all this was modeled from ford design as its an excellant starting point. Ford racers have went faster in small block door cars than any pontiacs in any configuration. Its a really good design one that is able to compete with big blocks carring twice the cubic inches.

The more the parts will interechange with the yates C3/ SVO heads the better as you can get shaft rockers, Ti valves, and other parts Cheap. Hopefully the flow will mimick these heads. We have a set of nascar take off oval ports that flowed around 380 with very small ports these heads are ancient being from 03. The blue thunder head would be a good pattern also as some have claimed 450+ flow numbers.

TRICK !!!

"Provisions for down nozzles in intake ports"?

For those that missed this statement, the reason for down nozzles would be for serious nitromethane applications (ie - current NHRA Top Fuel technology). I don't understand that, because at the current time, we're nowhere near maxing out the potential for a blown alky combination in the 6's, let alone a nitro' combo...and a conventional injection layout with one injector per port in the manifold and 8 or 10 more in the hat above the blower would be sufficient for running 5's in the 1/4 mile (provided we had the headflow and block to support the power needed...and even the Tiger heads aren't quite there for headflow for that kind of performance). Could be some extreme forward thinking there...or ???
