340 build up

I am planning on building a 340 for street/strip in my 72 demon. I have a freshly machined .060" over 340 block, stock forged crank, stock rods, and TRW forged pistons. When the engine is built I will have atleast 10.5:1 comp. For heads I will be using some big valve 'J' heads that have had just some gasket matching done to them. I need opinions on an intake and a cam. Also I will be running a set of tti headers and the car is a 4 spd. and will have 3.91 or 4.10 gears.
