Your heads flow VERY similar to mine. My cam in signature is close to the BTR S2. I sort of wish I had a tighter LSA, but overall, I'm happy with the cam. it really wakes up at 3K rpm. sometimes, it feels a bit delayed at the low end, but that could easily be tune.
If you don't have that notch in the head, you might want to go MLS 0.041" gaskets to get a bump in compression. That would leave you .035" quench. That's how I'm set up.

Never dyno'ed it. Just a street tune. I could guess, but it would be just that - a wild guess.
If I use my last quarter mile as a gauge, I ran 11.8 seconds. Running that through an internet calculator says 430 RWHP. That seems optimistic, to be honest. If someone chimed in with "you're closer to 410 with that setup" or something like that, I'd have nothing to counter their argument.
Regardless, it's very fun to drive, sounds impressive, and local mustangs and ricers won't even line up anymore at red lights

If I recall correct, the BTR stage 2 cam is almost identical in duration to the Tick Performance SNS Torque Max Stage 2 cam, which I have. 227/235 110LSA. It's a very nice cam. Sounds amazing, makes great power throughout the powerband, but really comes to life around 4000 rpms.
