Ported 241's question
 

I have a set of ported 241s they have ls6 valves 2.0 1.55 valves 65cc chamber. Here are flow numbers. Are these good flow numbers. Also was thinking bout Brian Tooley stage 2 cam. What u guys think. It's a street car. Has tsp long tubes and catted y pipe.
Intake exhaust
200. 144. 113.7
300. 207. 167.5
400. 258. 202
500. 276. 215
550 279. 221
600. 282. 222

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.

what kinda horsepower numbers u put down with cam and heads.

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.

ya its 227/234 614/576.

I was looking to make somewhere round 400 to rear wheels. hopefully I come up close to that

more and more, I think this would have been a better choice for me. I feel like I lost something with the 114 lsa. I keep thinking this is why I lost some of the low end. IVC could stand to be earlier. also, the additional overlap would sound nastier

Yes, the additional overlap helps the low end and sounds nasty. Mine pulls and keeps making power past 7000 rpms.
