There doesn't seem to be quite the market for cylinder heads as there was for the LS3, Partially due to it hasn't been out as long I am sure as well as the complex design requirements of the DI.... but the corvettes have been running the GenV for years now I figured we would see some more action.

I have not seen much in the way of cylinder head tech for them. PROVEN cylinder heads. I know companies like Vengeance and WeaponX have setups but there isn't very much results on how effective they really are

The little results I do find are back from 2014.

Has anyone found a set that makes sense ($ per HP) and that actually make power throughout the RPM band. Some of the flow charts I am reading aren't making power till 500 600 lift which frankly seems like a waste on a street car.

Am I missing something?

I will be working over a set soon. I will let you know what I come up with.

I think the missing part is the labor it takes to do H/C and the cost involved vs. just going FI. Plus at 59cc's and with the piston design I am not sure how much room for PTV there is to get your DCR correct for the cams out there. People like LMR, Vengeance, Weapon X have all been doing them for a while with good results from what I have seen. To me, it just seems to be a big runner with not a lot of flow from the factory. I am sure there is a bunch that can be done. I just haven't purchased a core head to mess with yet. Now that the MSD manifold is out as well you may see more builds that can take advantage of the extra flow.

I am really wondering what kinda of power they are actually making. I think the majority of it is coming from the cam. Obviously getting the combo perfect will make more power. But heads alone I would venture to guess couldnt be worth more than 15 hp at peak RPM.

I mean if I am going to put a cam in and have to take the heads off and apart anyway, I might as well but a nice set of cylinder heads back on...

Let me know what you come up with, I would be very interested in results.

I guess the only real way to test it would be cam first, test, then heads. I don't think ported heads would do much of anything with the stock cam.

Yeah but no results. Tunablility? Who knows. Most shops who are going to want to install head/cam packages are going to want to provide their own grinds. Assuming because of the time it takes to get it dialed in. I wish there was just some more guinea pigs lol. I dont want to be the first one! I figured with the C7 being around since 14, we would have seen alot more guys doing HCI packages. Then again, maybe they arent worth the money?
