My vote would be the tried and true Trick Flow 225's! They would be one of the strongest performers for your application, proven results on every LS2 I have seen reported on any forum.

What's your budget? TF and AFR are very good heads but pricey. They will make th bet power but other options include ported stock 243's for less than half the price. The 243's will most likely be giving up 10-20 rwhp depending on supporting mods.
It's all about what you're willing to spend

I saved money and bought the Trick Flow as cast 220's for $1600 and sold my stock 243's for $350, they had 45K miles and worn guides (long story) so my out of pocket was less than a set of ported 243's. I took the savings and had lighter valves installed and some hand finishing work performed, I am currently putting down 503 rwhp with them.

A set of new LS3 heads are about 600, CNC job is about 600 and a take off LS3 intake is about 300.
Sell the LS2 FAST for 500 or sell the LS2 FAST and get a FAST LS3, and you will get more power for about the same money.
Just my opinion.

I rather just change the ls2 heads bc i literally just bought a 102 intake. If i wouldnt of bought that i prob would of thought about that idea what you think stock ls2 heads with 60k on would be worth?

$1699 is pretty much the going rate for a pair of TF 220's fully assembled, several vendors sell them on here. Call a few to see who you personally feel the most comfortable buying them from.

Heads will be complete, just share the details of your setup with whoever you purchase from to make sure they set you up with the correct springs. Pushrod length will be determined after install, how much you take off the head surface and which head gasket thickness you go with etc to hit a target compression ratio will all have an effect on the length of the pushrods needed. Other items will include head bolts, lifters, lifter trays...will you use stock rockers or roller rockers? With the lift of your cam you could safely stay with stock rockers, just upgrade the heads to powdered metal guides. Valvetrain setup is extremely important!
A solid vendor/shop will help you put all this together but it certainly helps to create your own check list first to make sure you come up with a combination that works great together.

Here is another question for you guys... If i want to go a cheaper route...
Would it better to just port my 243's?
Or pick up some ported ls3 heads.
What type of gains ##'s would i see with ported 243s vs ported ls3 heads.?
Also will everything that bolts up to my ls2 head work on the ls3s? Tried to do some research no defined answer to my questions.
EDIT. Realized that 102 upper intake for an ls2 does not fit bc of the diff size of cathedral ports.
Also recommendations for a porter..not sure who does that and good work.

There are dozens of quality porters. I would recommend Advanved Induction, TEA, Livernois, Patriot, etc...
As far as the cheapest, it's probably most economical to buy LS3 heads and intake and sell the LS2 top end you have. You will make about the same power either way.

LS3 heads and ported LS2 heads will probably make within 5 rwhp Of each other. You will be able to sell that FAST in a couple hours for almost what you paid. Offer it up for $700 shipped and you be supposed how much interest there will be. That $700 will pay for LS3 heads and you can find a take-off LS3 intake for under $200. Sell the LS2 heads to a C5 guy for $400-500 and you may end up making a couple bucks.
