Default What heads for nitrous 370?

Ok guys, I'm building a 6.0 based forged 370 nitrous motor. I plan to try and get it as close to 12:1 compression that I can and run pump 93. I have a stand alone for the nitrous side. This primarily a track car, and it will have a single plane/plate kit spraying 400ish of nitrous to it. I have pretty much decided on tfs245's with btrs nitrous exhaust port. I just wanted to see who all has gone fast with different combos. I would be limited to a ported super vic with the cathedral heads, versus a cid with ls3 style. The amount of fast cars running the tfs245's is hard to argue with though

As you've already read the tfs245's are hard to beat.

That's my game plan, I figured people would argue one way or the other

Tfs are excellent. I went with the prc 237 due to a little bigger exhaust port.

+5cc mahle pistons h lite manly rods. Arp every where.Morel link bar lifters. Bushed rockers. Cometic head gaskets. Ran a 5.9 9.50 with an lsxrt intake, dry plate kit 250 shot. Holley efi .Cathedral port. A1000 for pump.bullet racing cam speced for 300 shot. Make sure you get the best lifters,rockers,
​​​lighest valves basically the valve terrain you can afford. For a big cam race motor I believe that's what's keeps it reliable.
Tune was off I was running e 85 and was was to rich. Broke up a little above 6500 rpms 11.2 afr. Feel on its face on the big end only went 133.
i am switching to super Vic accufab 4150 with a stinger plate this year. I got the stinger 2 kit with pro mod solenoids set up for 2 dry kits.

I have 2 lsxrt intakes if you new to buy one....
