Anyone do a straight across swap,from ported factory heads,to worked W-2's?

Again, I think it may have had a little too much gear. When I bought it, I talked with the previous owner at length about it. He ran the car at Irwindale in CA which was the 1/8, hence the 4.30 gear. I told him I was planning to put in a 4.10 gear I had and he thought it would be a good choice. He didn't think it would affect E.T. much if at all, it's only a 5% change. Might even MPH a little better? It's got a 28" tire and a low gear set in the trans. He shifted it at 6,800 and went through the traps at 7,000.

He also said it might benefit from a bigger carb but I have no plans for that at the moment. I am staying with the engine and drive train as-is for now.

I would think 4.10's and 28" tire would be perfect (because that's my combo too! haha). Is it spinning a lot? I plan for my car to be in the 10's and I am using a setup similar to yours. 11:1 motor, ported W2's, .645 lift 266/277 dur @ .050 roller cam, 1.5 Harland Sharps, Victor W2, TTi 1-7/8, 8" 5500 stall Dynamic converter with 727, 950HP, triangulated 4 link, 325/50/15 rear tires, etc. If he was going through 1/4 traps at 7000, that sounds about right to me.
