Edelbrock performer heads?
Stock ported heads done by the right porter will outperform those Edelbrock heads ALL day long.
The Edelbrock intake is nothing but a gimmick - the stock LT1 manifold can support big HP.
A 58mm throttle body is overkill for most builds and generally isn't worth the tuning effort.
For example, my car has ported stock heads and a stock manifold and runs its *** off.

And unless you're experienced I would say no to porting it yourself. Guys like AI and Elliot have access to CNC machines and hand porting experience when you need that little extra advantage.
Note that when you upgrade heads and cam everything starts to snowball and add up so if you seriously want to do a head and cam upgrade, triple the price for everything that goes with it to support the extra power levels.
Good luck.
Even at the "professional" level heads that flow about the same and make the same peak number on the dyno do not perform the same once sent down the track.
Heads and cam ends up needing supporting drivetrain stall/clutch upgrades, fuel system upgrades, suspension, replacement parts that you might as well put on long as you have the old worn original stuff removed.
My advise would be don't seriously start looking at buying heads/cam till at least mid winter spend all the time between now and then reading and asking questions.

Edelbrock's own numbers for their LT1 and LT4 kits are 396fwhp and 406fwhp respectively so they can't even make what the GM LT4 kit made with an intake that was internally the same as the LT1 intake and they designed it a decade later. You would hope that in a decade and with the "airgap" and everything else they could have actually made an upgrade vs. what GM already offered.
Their TB is fine, doesn't require any more hassle to make work than any other aftermarket TB. The heads/cam/intake though they seem to have been made just to sell some parts on name alone and didn't seem to much care about them actually being performance upgrades. I wish it weren't the case.
We are left with a bastard intake, a bastard set of heads, and a bastard block. I guess thats whats still great about the LT platform and sets us apart, you can go pretty damn fast on ported stock head and intake castings on a stock block.
People look under the hood of an old ford and say "holy crap a Flathead! I remember those!" Thats what the LT is going to be, nothing but a "dare to be different" engine come 10 years from now, the redheaded stepchild for GM that only us wierdos could love.

no kidding huh? guess tampax increased their prices lol
cost me 120 to fill my truck and 16.75 a gallon for the race car......whatever im having fun man thats what matters

keep in mind though the only thing stopping an lt from being this wonderful LS that everybody thinks is so great is a 3/8 drill bit and a set of sbc 18* heads that can be bought on racing junk for $1500......
the more i build ls1's the more i think they are throw away motors.......theres PLENTY of SBC Gen I motors out there outpowering ls1's with <18* heads....the ONLY advantage of an ls1 is the head......if u told me to build a serious race motor it'd be a gen I bowtie block with 15* heads on it ALL DAY over an LSx platform
besides ive upset moreeee than enough "serious" na ls1 guys with my little junk antiquated old school out of its time 23* headed small block
