We have been working on these for a very long time now and they are finally finished.
These heads are actually out-performing our 6.1 heads on our flow-bench and will be used on most of our builds moving forward. With the new motor going on Andy's car, I imagine a set of these will be going on at the same time. Justin will also be switching over to these in the not to distant future.
The First 5 sets will sell for $1895 and after that they are $2095.00
Let me know

Just curious...how much more CFM are they moving over a similarily ported 6.1 head???

451RWHP/439RWTQ
They are pretty equal, just a little more than the 6.1 in a couple areas.
Anyway to throw these onto my build?! I have an eagle intake already!

Core charges?
Do they require a 6.1 exhaust manifold/header. Nvrmnd, looking at the port pictured it looks d shaped so yes I think is the answer.

Do your Eagle Heads have stock chamber and valve sizes?
2006 Black R/T- Inertia 5.7 Based 370 with Eagle Big Valve Heads & Custom Blower Cam, Kenne Bell 2.8LC Supercharger with 148mm T/B & CTP'S KB Stand Alone Drive, Heat Exchanger & Oil Fill/Seperator, Dynatech Long Tubes & Catless Mids, Dynomax 3" Catback, Paramount Transmission, Dominator T/C, 3.06 Getrag with DSS 1400HP axels & Drive shaft, Willwood Brake Upgrade Kit and AFCO Coilovers. Best ET 10.49 @ 129.72
2012 Black RAM 1500 Sport 4 X 4 DS InTune, BT Catch Can
The valves are manley, 2.08" and 1.575"
Chamber is worked to be 11:1 on a stock pistons. Chamber work is kinda per order, depending on if its for a stroker, stock 6.1 or stock 5.7 and what the customer whats for a compression ratio.
So whaddya do if they're going onto a stock piston'd 5.7 now, and eventually go onto a 6.1??![]()
Hemi Registry 0436 6.1 block - CTP Dual intake - Modern Muscle ported intake manifold - Indy Heads - PWR cam - FTI converter - TTI Longtube(catless) - 3.06 gears - 17 X 8.5 Borbet TS w/ 275/40 Hoosiers - Diablo tuned!! Billet Tech Goodies EVERYWHERE. ALL Parts supplied by LXF vendors: Afterhours Mopar Performance, SpeedRated, PWR, Modern Muscle, Picklefork...and LXForum members. Installed by: Afterhours Mopar Performance
Compression ratio would drop going from a 5.7 bore to a 6.1 bore.
If you changing the short block I would think the easiest route at that point would be to get the pistons to match the compression you want and leave the heads alone![]()
So will these work on a stock 6.1 block with no new pistons? They'll slap onto a stock 6.1 short block?
