Cam suggestions
05 Corvette stock ls2 other than black widow exhaust and vararam cai. Currently in the market for a cam kit I'm looking at the BTR stg3 N/A cam kit specs are Specs: 231/242 .617"/.592" 112+2.. 243 heads will be getting ls7 lifters , planing on throwing in a 3200-3500 stall and long tube headers for now. once Im done with that I will be doing 823 heads and ls3 intake. I'm looking for a aggressive cam that makes power on the top end. Suggestions and tips are appreciated thank you

Thank you both for your suggestions and intell I will be ordering the parts this weekend and keep y'all posted on the work. As for the cnc port I've got quotes and cost just as much as the ls3 heads on the bright side I can always throw a lsa super charger down the road but that's another story

Don't forget that you'll be losing static compression ratio going to the LS3 heads. And you're limited on how much you can mill the heads with an aggressive cam profile unless you flycut the pistons. More static C/R tames a big cam somewhat if manners/drivability mean anything to you. Plus it makes more power. CNC ported LS2 heads are pretty much the equal to stock LS3 heads flow wise.
I'm about settled on an LS2 build. I'm going to have Tx Speed CNC port and mill the stock heads .010 as well as use a .040 head gasket. Static CR should be around 11.6:1. $850 for the CNC porting, milling, multi angle valve job, cleaning and assembly with my valve spring of choice. I'm going to use a high rise ported intake manifold to top it off (not going in a Vette). If it were, a FAST intake mani would be the ticket.

@old motorhead I am leaning towards porting the 243 but I got a quote today for $2,030 just for the cnc port if you guys know of a local shop around California pls let me know I'm from l.a , for that price I'm better off buying aftermarket heads but do not want to go that route. This is not my first time working on a car but it is my first performance built so if you got suggestions on how I can make my ls2 more reliable pls let me know

I missed the part where you were in California. If you're limited to 91 octane fuel, you probably don't need a higher static CR. Maybe do the LS3 heads with no milling and a .040 head gasket to tighten up the quench area.
Can't help with your cam choice as cams like you're talking about are out of my league. The biggest cam I tried in an LS engine was way too big for me. And it was smaller than the one your referenced in your original post. I enjoy my smooth and efficient vs chasing HP over 6000 rpm that also comes with drivability issues.

Currently in the market for a cam kit I'm looking at the BTR stg3 N/A cam kit ... specs are 231/242. .617"/.592". 112+2

if you guys know of a local shop around California pls let me know .I'm from LA.
You say your from the Los Angeles, California area ... How do you expect to pass the new California smog inspection after modifying the car's computer program and installing long tube headers ?

Of course, after installing that big cam in your LS2, you will need to get it dyno tuned ... And you want to install a set of long tube headers.

so far from the truth. A converter like a ss3600 yank converter can be used on a stock motor and make a huge difference. Better mod than a cam. Small cam like a btr2 would amaze you.
