I'll post some flow #'s I have for the 6.1 and the newer 5.7 heads pictured here.
I won't have flow #'s on the older 5.7 heads for about 2 weeks but I'll post them when I have them.
I'll post some pics of the other heads in the next few days.

Cool! Do you need a set of the older heads?
I am not causing global warming, I am just trying to hold off a impending Ice Age!

Maybe! The heads that we got with the block on our 5.7 have the seats falling out of them. I can fix them, and was planning on starting with them stock, then ported then moving on to the late 5.7 heads pictured here.

Looking forward to reading about your results. Can you give a rundown on approx. price that goes along with building one of these engines as well?

I will be watching this close Brian...next engine I build I would like to do a new hemi.
Are you going to be hand porting these hemi heads, or developing a CNC program for them?
I'm glad to see I'm not the only one excited about these engines.
We are looking at a cnc machine in the next year or so, but for now everything is hand ported by me.
We are doing CARB only as I believe there is a strong market for guys who want easy to tune engines mild to wild.
I'm talking with Edelbrock now about some things so I'll mention the intake. I think a dual plane done right would be the way to go for mild builds but we'll see what happens.
I will flow this late 5.7 and an early 5.7 tomorrow and post the flow curves later on. I also have a pair of 6.1's that I've flowed for comparison.
I'll try to list the AVG CSA of each head as well. The crank Scat has is 3.900 and 4.050 I belive but I'll check on that.
I'm also going to sonic test the 5.7 block next week and go from there.
Brian
Why the long wait?

SS: right now it seems the little LA engine is our hot topic. We build about 40 of these a year! And it seems everyone is kinda doing there own thing with them. Plus now there's decent parts to go CARB which is my personal preference.
Rich...ha ha! I read it. I'm not surprised in the least. Once again the HEMI brings some drama to the table!!
