In the middle of installing new parts and need.... help/advice

[Dark_5.0]

Ok my car is all taken apart and this is the deepest I have ever gone into a fuel injection motor.

I have new parts to install GT-40 intake , port and polished stock heads and 1.7 roller rockers.

Question #1...should I use the 1.7 roller rockers or would I get more out of a b-303 cam.

#2...Does the GT-40 intake flow too good for my current set-up

#3 Is it time for a custom burned chip or would it be a waist of money on a SPEED DENSITY setup

#4 Will the GT-40 intake clear tall valve covers or will I need a spacer.

#5 When I put the injectors in the GT-40 intake do I lube them with anything or just pop em in there

Any help would be appreciated....Hoping for LOW 14's I also have subframes and slicks to install before march when the track opens
