What Heads?
^^This. Believe me I'm dying to know as well but I have no intentions on getting stranded in NJ. There is a test n tune 4 miles away at the local FD Oct 21st. It's only a 330 ft run but it's something. Won't be making good 60ft's but maybe I'll get a good mph out of it.
After the 211/219 cam install I drove from DFW down to HRP to test out the cam on my snazzy hypertech tune. Broke the Zexel Torsen in half and chipped a few teeth off the ring gear on the third run. Took almost eight hours to drive back going no faster than 40mph. Everyone needs to go through something like that at least once.

My favorite track is 150miles away never trailered to or from. A dyno number without something to back it up is pointless. My old cam only setup I had a graph that said 509tq and I know a guy with a 9second Impala that had a dyno print out 400rwhp. Both of those numbers are bullshit but they were what the dyno said.

The ET is **** poor but the MPH does support the engine making that kind of power in a normal weight street f-body.
This is why I specifically stated "track MPH". A soft launch to spare a POS 7.5" will hurt ET a lot more than MPH we all know this.

My friend on here "studderin" dynoed near 430rwhp and was trapping 129mph. Yes he was lighter at 3200 raceweight for the world cup race last year, but 9 mph is huge. Look at speedracers 60-ft time. If he would have hooked he would have run a 11.5 at around 117-118 with say a 1.7 60ft. Hardly 430rwhp.

.120 seems low for 430rwhp but I don't know his raceweight or DA so who knows

This, not everyone has a ghetto fabulous tin can race car. I'm sure the 4.10's and shifting a few hundred rpm higher would probably have helped too. And the lower i 60' the higher i trapped.

I looked up the DA for his friend's event and it was deeply negative that whole weekend, 4pm one day was -1000 the next was still -700. It was a November event at MIR.
Rolling into the throttle and getting a bad ET that way trying to save a POS 7.5" will hurt MPH a lot more than flooring it and blowing the tires off will help MPH. We do see cases of a bad 60ft helping MPH but those are wheelspin not soft throttle launches.
Something like a TH400 puts up a bad dyno number but sometimes helps at the track if the car had the 1-2 shift dropping rpm too low. Point being dyno numbers don't tell the whole story and neither do track numbers for that matter but you can get a feel for things if you are actually interested in understanding the variables. 300lbs a couple thousand foot of DA, a hard clutch dump on an S60 as opposed to babying a 7.5" those are BIG variables and I wouldn't fault anyone for leaving soft with a T56 and 7.5". Hell I had to put a new Auburn in a friend's third gen 7.5" axle because he cracked a spider with a T56.

The Lvl 2 Fuddle "3000" was pretty loose and I'm sure it was eating some power, but it sure was fun at the track! My tuner noted that on the dyno it behaved like a 3400...
Thinking an ATI Treemaster 4400 on the new combo though. Should be a bit quicker...while still being a street car of course.
As for the OP, there are a million heads that can get you that goal - its up to you whether you want ported stockers for now, or aftermarket heads that will also make your goal but leave more room to grow in the future.

God I love head or camshaft threads.
For 370rwhp to 410rwhp goals... [rwhp goals are sort of pointless to me because you can do a cam only 370rwhp with a peaky graph and little usable power or 370rwhp with heads and a camshaft that makes good power across the board] ...regardless AI, LE, LPE, GTP, TEA and any other good head porting company can get you to that goal with a well matched camshaft. Research, call them all, take a hard look at your budget, expand the budget, research, see what you're getting for your money, look at their track record, research, and spend accordingly. Honestly it could also be done with out of the box heads as well, just make sure you get the right cam in there. Out of the box heads are nice if you want to get them ported later. But remember heads and a camshaft are only a few pieces of the puzzle, even the best heads or cam can be paralyzed by mismatched parts or poor planning.
