Heads or no heads
1 Re-gasketed everything I could while the engine was out.
2. Cam - TSP 228R with .600 lift and 112 LSA
3. LS7 lifters
4 Double .660 springs locks and retainers
5.Cam chain and sprockets
6.Chevy performance oil pump
7.BBK 1 7/8 headers
8. Ls1 Trunion upgrade roller rockers
9. Front and rear cover plates
10. Already had 3:42 gears and an LS6 intake
11. I also picked up some used 243 heads that were in good shape.
12 Tune with four dyno pulls car made 401 HP. rotating assy had 150k on it.
I'm sure with a different cam, as the 228r is not a radical cam, you could easily make 420. Learn how to drive at the track with some good tires and it could happen.

If your goal is consistent mid-11's at full weight, I don't think you'll get there with only the mods listed on the Slohawk quote. I'd guess more like consistent high 11's or low 12's depending on D/A and 60'.
Good luck and Happy Thanksgiving!

Franz, check out this thread: https://ls1tech.com/forums/11-second...1-831-a-5.html He's running mid-11's with an LS6 intake and cam but has 3.73's. Opposite of what I recommended so you might pay attention to his build instead of my advice. His cam is a little bigger than the 228.
I would not be the least bit concerned about the 10 bolt behind a auto. I have 3.73's in my 10 bolt and pull 1.5x 60's on it and am not remotely concerned about it
