Depends on what your definition is basic is. You understand that LS1 valves are metric and fitting them to an LT1 head would not be "basic".
Ported LT1 heads are capable of substantial power, the company I used has several cars iin the 500rwhp area and more recently a couple of 429rwhp street cars one a 350 the other a 355. Most places are not going to be able to duplicate such.

Flow #'s sell heads, that's it. There's people with supposidly badass topends running pathetic times for their setups, and then theres people with supposidly weak heads running as fast if not faster than those guys with much less. I would buy heads based on track results, not flow #'s.

Advanced Induction did both my heads which are their obsolete 190cc version and speed_demon24's new 200cc that he recently put 429rwhp down with on a stock shortblock.
Last trip to GLD my worst pass of the day at about 4200lbs was 12.2 and mine is a true virgin shortblock, never even pulled a bearing cap. Like I said my heads are not even offered anymore they have a better setup with better springs.
Here is a video from last fall.

There is a guy in New Berlin with a heads and cam like this too. Maybe the best thing you can do if you are on the fence is to wait till spring and check out a few cars.

On average an Impala wheel and tire combo is say 58-62lbs each. Those were what was on the front of the car in that video.
Far as cars running numbers and how they are setup, I have seen cars that run well with crappy parts due to a good wrench and I see A LOT of cars that run poorly because a bad wrench made poor parts decisions compounding the problems.
Too many reputations are built on 1-2 cars, averages mean more because it is less likely it is just a skilled wrench making crap work.
I think it important to try and have some halfassed idea of what it took to get a car there too. I can point you at an Impala running high 10s in almost all weather NA with GM heads and intake but others swear you need aftermarket castings and single plane intakes and all sorts of crap to make lighter cars run that
.If I have a choice of listening to a guy who made a car run say 11.0 for 10K or listening to a guy who made one go 10.9 for $15K, I will listen to the one who went 11.0 for 10K because he is making better decisions.
