I am looking at the Edelbrock 60069 heads. I am currently running C6AE-R with 2.09-1.65 valves with a little chamber work. Would the increases be noticeable, or just a weights savings of about 40lbs?

If you make no other changes, the mid-range will be stronger. Not profoundly stronger, but seat-of-the-pants stronger. FE heads are not all that bad in actual performance. Yeah, I know the flow numbers for a lot of the garden variety heads are not all that outstanding, but you can't drive a flow bench. So, you're swapping a low rise head for a medium rise head. The combination will determine your true outcome.

It's on my '67 Shelby. I am running the original C7ZX dual quad. I think the port alignment will be better as well.

I would say yes. You will a noticeable increase in power. Might be 20 hp depending on the combination. Combined with the weight savings (36 lb), I think it will be noticeable. Not huge, but noticeable.

If they did any blending to the larger valves, i don’t think you’ll see much difference. MR intake to LR head is fine
