Head Recommendation

Can anybody give me some advice on the best available (strip only) head to use on a small block 416 stroker. I'm currently using older (cast iron) W-2's that are pretty efficient, but I'm sure there is better available...........
Currently doing about 126-7 MPH (on a good day) in 10.5-6ish seconds. My short block is rock solid, Victor W-2 intake, 950 Holley HP, 430 spool Dana, 30 x 9 radial slicks & Caltracs with a 904 with a 5500 TC. The combination is in fine shape and works well.
I'd like to get some better breathing, as well as I'm going to lighten up the front end with lighter wheels, a glass bumper and maybe a rack front end this winter.
My goal is to hit about 138-9 MPH in around a 10 second flat run.
Appreciate the advice.........
Daryl
