Brand new large chamber iron D3-style 429/460 head castings with modern exhaust ports

I was checking out another Ford website and you won't believe what is now available for us big block Ford fans: BRAND NEW large chamber iron D3-style 429/460 head castings with modern exhaust ports!

I was excited to see that there is another choice for enthusiasts out there who need a casting like these for a truck, motorhome, street machine or class restricted racing.

I do not know anything more about these heads than the information below that I copied and pasted from the other webite. Check out the link near the bottom or call Scotty Johnston at RHP for more information.

These brand new castings feature:

Completely revised and updated standard location exhaust port flowing 180 cfm as cast.
200 cfm with bowl blend
240 cfm with large valve and port work.

Hardened seat inserts on both intake and exhaust.
Additional material around exhaust port bolt hole bosses.
Additional material cast in above valve seats intake and exhaust.

95 cc combustion closed chamber.
Slotted oem style rocker pedestals accept stock rockers or aftermarket bolt down rockers.
Uses standard 26 autolite spark plug like the OEM version.
.380" thick deck. Can be milled down to 88 cc's.

OEM intake port configuration with additional cross section at pushrod pinch and short turn radii.

Ideal for propane or CNG use.
Suitable for HD and motor home / heavy towing use.
Flow rates with large valves and portwork will support 750 + HP in a max effort pulling or racing application which is class restricted to iron heads.

See link for more information...

They look good, nice to have another option...I wonder about the alloy and I'm guessing China. But again they do look/sound good

Cylinder heads were redesigned in the US, Cast in China and machined in the US as the scat line of products are.

The alloy has less nickle. The casting quality, detail and finish are all very good and are reasons why I elected to carry them in addition to a very good exhaust port design.

How much do a set go for and do they have plans to make any 75cc chambers with stud mounted rockers like a set of 1968 heads?

Purdy, let's see a build and dyno test with um. How long have they been out and is anyone using them? As stated, it would be nice if they had smaller combustion chambers and screw in studs. A moderate bump in compression (maybe 1 to 1.5 points?) would be a nice addition to the improved flow numbers. I suppose you could cut them, but that is an added expense and opens a can of worms with valve train and intake manifold geometry correct? I want torque and lots of it!

Would like to see some flow number's?

All the flow numbers showing are at .800lift. I would like to see some numbers around .500. this is where most towing cam run around. Looks like a great product but need some more info. thanks from wyoming. Also are the heads flowed at 28"water or at 14"water not mentioned? Probably at 28" just want to be sure.

Deck the block, not the heads.
Pistons are too far in the hole to start with.
I will be checking out the "other" forum for more info on these heads with their improved exhaust ports.

Thanks for the heads up Dezertracer.

It's nice to see a iron D3 with a exhaust port that doesn't have the smog in it. Would have been nice if they would have been machined for studs and guide plates though.
