It's great that Eagles are so capable. I figured you'd just get the Apache to 65cc and go. Don't you have a flat piston? Are you going for 13.5.1?
Mopar to the bone!!!

Im at 11-1. if I put the Apache on it would drop to 10. My thought is any hp increase in cfm would be lost with Comp. you would really need to deck the crap out of the apache head to get it down below 65cc. if your starting fresh like Dustin did and plan for the 75cc chamber then your golden but my pistons were planned for Eagles. they are -13cc slight dish piston. I had also contemplated getting the thitek porter head. But they have so much extra material I think to design your own port I thought it may take years for me to actually finish them. so this is my plan of attack. also, when someone asks about the engine I can still say, its just 5.7 heads on a stroker shortblock

How much do you want for your apache's ? I plan to use the valves from mine. I planned on putting them on the shelf for maybe a build later down the road. one head is ported and one isn't

next thing I want to try and big Thanks to Dustin for sending some banged up heads, is stuffing the 03-08 5.7 head with a 6.1 valve. I really think the original 5.7 heads can be an awesome high velocity head which I would think 320cfm around .6 is easily possible because I hit 312 opening the throat probably a little to far

Im switching back to the Eagle head. My delima was my Apache port only flowed 20 cfm more than my Eagles that Im running now but the chamber cc is 75 for apache vs 65 for the Eagle. I would lose a whole point of compression.
My next dilema was the Thiteks. I got to flow a set of Thiteks last saturday and they are awesome. On my bench they were within 1-3 cfm of their advertised numbers. But the way they reduce chamber volume is by milling the head. The chamber is 70cc and they mill it .030 to get it to 65. I would think if the valve is in the same location the that gets P to V clearance closer. And I want to try to get my chamber to around 60 or less if possible.
So tonight. All i had was a 45 stone that fit. So with one seat angle and opened the throat a little with a carbide burr. Flow went up 20cfm. Another 5 minutes of messing around got me almost another 10cfm. With the throat at 1.83 the head is flowing right what a stock apache does. Port sounds alot quieter also.
I figure with .020 mill it can give me a nice bump in comp and maybe even outflow the apache. The roof is different in the eagle and may turn out better Thanks for the info Ray. I know your bench and my friends are very close. About your apaches. Could you weld up the chamber some to decrease volume? Matt

Matt I considered that. but its like bondo. you have to put a lot of weld in then take a lot out. Its not like a wedge head where you might add weld to one area. you might decide you want to weld up both sides of the chamber. Then pay to have it decked. your looking at piles of time and money. The apache intake valves are $60 each. expensive but you can probably get a solid stem replacement much cheaper and have someone fit them in an eagle head.

I plan to get have them flow tested locally as the claimed flow numbers seemed inflated to me, if they are suitable I will have chambers welded closed and use them.

That's an Eagle on the bench. The port on your early 5.7 is still much smaller. I spy Harlands

I spy Harlands Yeah, the guy I bought them from sent them to harland to have them design adjustable rockers for a solid roller set up, they eventually gave up and sent them back to him with a hodge podge of parts and told him if he could make any of it work to let them know what he came up with lol

the 2.18 wont fit on the eagle seat. not even sure if the 2.14 will. it will be near the edge. the 2.18 would be a nice upgrade for the apache I bet. But you will need to plan your piston
