Magnum heads on LA block H.p increase

Reading through this post hearing the pros and cons of the magnum heads and just wondering how fast some of you guys have gone with them. I’m honestly impressed with what I’ve seen out of a set on a friends engine. What do you guys think a 408 magnum engine with a hydraulic roller, flat top pistons, ported magnum heads with 2.05 intake valves, 750 alcohol carb, powerglide, at 3200 pounds. What do you think this combo would run in the 1/8 mile.

to fill in the blank on this this engine has gone 6.70’s (10.50) but he loses almost .20 as he foot brakes the car a lot and when he does he “deep stages” the car. So I can’t remember if this was deep staged or not. I do know his Dad has had a set of TrickFlow heads and is hesitant about putting them on till we do some flow testing on my flowbench. He’s kicking around at least putting a 2.05 valve in them before running them. Like I said before if I had a mule engine, still enjoyed working on cars, I would probably port a set (magnum heads) as they can be a damn good head.
