Invest in a set of TFS as cast 220s and s fast 102mm. Done.

He already has the 243's so he should already be there?

Get a 243 intake which is WAY better than the LS1 unit. Not sure on the injectors...

Ported 243 heads can get pricey. Couple more hundred dollars and you can go TFS like I recommended. Everyone port work isn't the same in performance, price and quality.

TSP will do a stage I port on 243's for $750, larger valves (this makes it a Stage 2.5) and/or different springs are extra.

From what I've seen with my own eyes is that TEA have the meanest port program for a 243 head. They have track times to back up their work but they not cheap by no means.....

I suppose it comes down to bang for the buck... I think TSP's porting is more conservative, not taking out much material and concentrating more on smoothing the flow.

More than a set of ported heads. A good valve job, multi angled on the intakes with a back cut, maybe a radiused seat on the exhaust (serdi) and a good intake manifold to support it will make the OP’s goal

Op, all dynos are not the same. Dynojet dynos are friendly.

Stock 243’s will support 450 rwhp easily

Enough of the 450whp bolt on ls6 nonsense. Your full of it and everyone who has basic knowledge of engines knows it. I have spoken with experienced tuners and engine builders and they laugh at this notion when I bring it up. Find an honest dyno and stop plauging these forms with lies and if your not lying, you were lied to by your tuner and Dyno results, you are impressing no one and just make yourselves look like fools to those who know better.
Headers, exhaust, fast 92 and 205-215cc afr/trick heads with a mild street cam will get you in the 450whp territory. If you want more then I'd build the bottom end with good lightweight components and low friction rings and add a fast 102 and a bigger cam paired with heads that will satisfy 7k+ RPM demands for air. And a revised fuel system to support it. You could also free up HP from power robbing accessories but this imo isn't worth the investment unless you want to squeeze every ounce of power out for bragging rights.

get a ported FAST 92/92 setup 1 7/8 headers make sure you have a good flowing catback. upgrade that lid to a Fast Toys 98mm lid, do away with the MAF and have a good tune put on it and you should be damn close. if not have those 243s ported and it will for sure make that as long as the tune is good.
