Default LS1 347 Heads and Intake Questions

Hi guys, I have 99 z28 M6, mods are : 347 rotating assembly (Callies Compstar H beams, and Mahle forged pistons), poly motor mounts, lid, LTs, ORY, cutout, TSP 228r (.588/.588) @112, 42# injectors, hotwire kit, tuned by Lashway.

I have a buddy of mine that has a z06 that he has built from the block up. He kept onto his 243 heads with upgraded springs (car had a cam when he took heads off) also has his LS6 intake. He moved to a FAST setup.

Now before I would install the heads I would get them worked on. But my question is this, should I sell the intake and take that money and buy a 92 or 102, which would require new fuel rails, right? Anything else I'm missing, besides a TB.

I'll be buying the intake and heads for about 600.

My goal is to have an 11 sec car N/A, car is daily driven until I find a more suitable daily. 250 shot in the future.

Thanks!

Car currently make 387HP/377TQ

Haven't been there on a day for times yet. Mid 12's would be my guess though.
Still learning to launch the car.

You may already have a high 11 sec car!! Learn how to launch that car or even take some suspension work into consideration......

I have been looking into suspension more and more. Car is currently on orange decarbons and stock springs as well. Has the 'classic' 4x4 stance lol

Car does however have a random adjustable torque arm.

LOL!! No need in adding power if the car can't manage it. I would focus on getting the power you already have now to the ground....
tires, shocks, springs, sway bars, etc... plays a BIG role to getting the car to its full max potential.

BMR springs, HD bilsteins, panhard bar, I know UMI makes some good stuff but suspension is new to me, not sure how everything pieces together, or what to look for.
