Best heads and intake?
Depends what your looking for and how much money you want to spend. May be fine with some ported stockers or maybe you would be better off with some aftermarket castings, really depends what your looking to do with the car.
I recommend Lloyd Elliott for your head needs:

As for intake, for most a ported stock LT1 is all you need. If your going with an all out super crazy build then there are some better alternatives but they very costly. For $200 Lloyd Elliott can also port your stock manifold.

Both LE and AI make great heads that would work perfect. I went with LE after speaking with both companies. My car is a 355 LE2 heads LE custom HR cam(smaller than a 847) and runs 11.6 at 119 with tons left in it.

My car is a lightweight (3825 lb) ImpalaSS and went 11.31 @ 120 with AI 200cc LT1 heads and AI custom cam on a stock shortblock. It'll go quicker when I get to a track with some hook.
After having ran an AI cam, (which was the smallest and quickest cam I ever ran BTW), and met Ron and Phil, and seeing the results and quality of their cylinder heads first hand I would go with Advanced Induction
We all know both companies make great products, I chose LE for several reasons customer service, Price and also a proven product ( Yes i know A.I. also has a proven product as well) OP this could go back and forth for infinity. You need to call one or both of the companies or maybe another and make up your own mind. I say both are excellent, Just need to talk with them and get your own opinion. And Good Luck with it ! !!!!!!! !!!
Good to see you here Pat.
My last time out the worst 60ft. was 1.58 and I was running 11.8s, get that to hook and you will drop more ET.
