Up Grades on Stroker-Suggestions

Going through this with my barracuda at the moment, the where to from here with a mild 408.

To give you an idea, my 69 barracuda with 3100 stall, 3.9 gears, 727 and a 408 with 248 solid cam and stock w2 heads ran a 11.72 at 115.5mph at the mopar rumble drag day in sydney last month,not super quick but still ok for something I can just jump in and drive anytime.

My thoughts are a bigger cam, dont know about you but my 248 solid is very tam and getting the heads ported. I don't think stock heads, either edelbrock or w2 are good enough for 408 cubes.
