Figured I would share these pics of the new 6.4L cylinder heads!

 

[rubbel]

Valves look larger than the 6.1?

 

[PWR_Andy]

These have 2.13" Intake valves and 1.65" Exhaust valves compared to 2.08" x 1.59" on the current 6.1 heads. They share more in common with the eagles than the 6.1's.

Can these bolt on the 6.1 and go........FASTER!!

 

[rayzazoo]

Ooooo these look nice

What are the specs on the current eagles?

 

[InferAl]

Very Nice :bigthumb:

Me likey these. What are the cfm numbers? 2.13" and 1.65" are pretty damn big from the factory, right? What are the valve sizes from the aftermarket?

 

[jzimnisky]

Hummmm, I have ideas.
Would these do any better for boost then Mine???

Interesting I don't see any quench area. Are those stock Mopar heads or some custom castings? The 5.7 has them and doesn't put out near the power the new 392 is. I assumed every emission cutting mod would have been done no questions asked at Chrysler.

Either way they sure are beautiful!!

So will these bolt on a 6.1 without any major mods?

 

[PWR_Andy]

They will bolt up no problem. We are going to verify that everythibgworks togather and doesn't leak coolant in the not to distant future.

Andy,
So is there any noticeable difference in the port configuration on 6.4 heads compared to the 6.1?

 

[PWR_Andy]

The windows are almost identical. The exhaust port doesnt look that good so far, but we will find out today how good they are. I should have flow numbers today.

 

[daparrothead]

Thanks Andy,
I just don't want to over look an oportunity when I get ready to have you build me a motor soon hopefully, I really want to do a 440 build.

 

[tony292]

Andy how do these compare to 5.7 eagle heads?

 

[PWR_Andy]

I will offer a full write up as soon as flow data is in. So far, they appear to be superior to all current heads.

360/205 in stock form. Complete flow sheets to be posted tomorrow. Now its time to port them.

 

[randycat99]

That is an interesting point about the removed quench areas in the cylinder head. The 6.4 has a similar compression ratio as the 5.7, no? Is it filled in more somewhere else or in the piston to maintain the compression ratio?

Were the 360/205 flow test at 600? Are those test run on a superflow 600? Thanks andy:thumbsup:
