You were all for doing a cam and wanted to retain driveability and pass smog etc, heads will get you there but a cam won't. But you're avoiding heads like the plague. They're not any harder than a cam swap, honestly I'd rather do heads than a cam swap and I've done both. The heads will do everything you wanted and a cam won't..

If I was going the legal route I'd plan on going with this.
With CARB shorties, ported stock heads and it should net well over 400+ hp daily street power.

Why so against doing heads?

I was exploring my options and it seems that heads are one of the most efficient ways of getting where I wanna be. I was under the assumption that a cam with the necessary supporting mods would be enough, but it is now clear to me that there is more to it than just throwing in a cam and calling it a day.

I daily mine with a Torquer V2. Streetability is great and it's tons of fun. It made 413 whp, however, every dyno reads differently, so numbers aren't everything by any means. I have a feeling it wouldn't pass smog though.

OP, if you want to go faster, there's a lot of ways to do it. Many of which won't cause you to fail inspections either. Unfortunately the cam is going to be the worst option you have here. Hio has made a lot more power than I have with a stock long block car, but I used to bust cammed car in my full weight stock long block (stock heads, cam, etc) car. It's all about making everything work to it's potential through a well put together/matching simple setup.

I found a bunch of results from a google search...
LS6 heads would not be an option if you want to keep it 100% legal, but those AI ported 241 heads with welded chambers mentioned above, or AFR 210 heads would get you to your goal.
Again, sub ported 241's or AFR's for the 243 heads...
This last poster was from Texas, which is why he would not know if his setup passed smog in CA. It's just another example of a well refined setup with stock exhaust that makes the numbers you are looking for.
Good luck with your build!
we've had the tsp 224r camshaft on a 114+4 pass smog in cali before. I think that's getting to be the limit though..

hey man im out here in ca too. My roomate passed smog (sniffer not visual) in his frc. He had a 224/224 and made 447rwhp with lt's, fast 90/90, ported ls6 heads, a pulley, and a really good tuner. The fast is a dead giveaway for visual but without if your not gonna have that all you gotta do is just keep the stock exhaust and swap it back on when you have to smog and do a lil retune. (that is if you cant find someone to "help" you out). Thats all you gotta worry about since the heads look stock, and youll never see the pulley.
back in 2000-2001 in the local fbody club we had someone try to make 400 whp with the stock manifolds and cats. With a 216/220 cam, more performance stage 2 heads, under drive pulley, ls6 intake, cut out and other supporting mods the car made 360-365 rwhp.
Passing the sniffer test was required so cam size was limited. This was before ls1 edit software was popular and the pcm tuning wasn't as refined as today. There weren't any electric water pumps or affordable roller rockers either. He was stuck with the stainless steel exhaust manifolds which don't flow as well generally as the cast iron ones from 2000 up.

this was a very cool project. Ray pesek from port o'connor texas has a gorgeous 1937 ford business coupe that he put a bone stock '99 ls1 in. I tuned it and it made 332rwhp/347rwtq. Ray decided he wanted more power, but he didn't want to spend too much and he had to keep the factory exhaust manifolds.
With help from geoff from engine power systems, we formulated a budget sleeper approach. We would add bone stock 243 heads (unported and unmilled), add comp 918 beehive springs, swap the ls1 intake for an ls6 intake and make a custom cam using engine power systems custom eps lobes. These lobes have been making incredible power with beehive springs. The way this motor revs is a thing of beauty. Cam specs are 218/230 .595"/.600" 115lsa +4 advance. The new power was 403rwhp/392rwtq. A gain of 71rwhp and 45 rwtq.

patrickg specified my cam.
Because i wanted a cam that worked with stock exhaust manifolds as opposed to headers it is relatively mild (218/230, 600 lift) and is on eps lobes. It was originally installed with stock heads and stock rockers with the usual supporting mods (push rods, timing chain, dual valve springs). Later i went to trick flow heads with different push rods, jesel rockers and a fast 102 intake (which is known to amplify valvertrain noise). Neither of these setups exhibit any significant valvertrain noise. So i have no reason to conclude that cams with eps lobes are inherently noisy. They are known for being easy on other valve train components.
In any event patrickg specs cams on other lobes and can be reached here:

Because the object is really to get better acceleration......not which cam, heads or how much it dyno'd.

now maybe a 150 shot and 3.73/3.90 would work. A 150shot would run over top 4.10s way easy.
