Just a dumb question because I have no idea but what would this do for my stock 6.4 m6 if I put these on?

It would need to be packaged with a higher lift cam 2 see good gains on the stock 6.4 l motor

Which would work well if you figured out a higher lift cam because these heads are complete with the 650 lift springs already on these heads. Let me know if interested. They are currently at A2Speed in Va where i am having mods made to my car

For an idea on the power gain.

I just did ported heads with a 274 cam, LTH with hi flow cats. Dyno tuned.
Rwhp increase was 51 and rwtq increase was 34

Correct its all gonna be dependent on what all you have done and how well the package works together.

No issues with the heads. They are great heads just changed to the thiteks because they are known to be better and flow better and the dual bolt pattern on the thitek heads because i have the hellcat front belt setup on the car.

Apache are good heads, but I found they would not take a lot of boost. Seemed ok at 14lbs, but when I went to 20lbs they did not hold up. Price is right for these heads and if you are not going to do a lot of boost it would be a good upgrade.
