Intake options
So it has +2 advance putting the intake valve close at 42.5? All the 4 inch stroke LS's I'm familiar with like 47 to 52 intake valve close. Doesn't seem a good match for a 383 stroker to me. ~20 degrees of overlap, I bet it does chop. TSP doesn't list the cam as recommended for stroker applications just 5.7's and 6.0's. I consider a different cam for your 383 LS. Maybe others will comment.
What stall are you running or plan to run with the new 383 LS?
Specs: 251/266 .62X"/.595" 112+4
That's an amazing cam based on what's on the BTR website. I'd want match it to the 400+ cubic inch engine, TFS cathedral port heads and Mast intake, it was developed and optimized to use. With ~34 degrees of overlap seems like a very serious 😳 big cam for racing 🏁. I'd ask BTR what stall and gears they recommend.
Cammotion stroker-ls-camshafts has a lot of possibilities. May be ask Cammotion to help with cam selection. This might be in the ballpark...sort of inbetween the TSP & BTR cams mentioned.
Street King Stroker LS Camshaft (244/256-112+4)
As for intakes, either a ported Fast 102 or ported MSD. If spinning 7,000+ rpms the MSD, otherwise probably the Fast 102.

EDIT: having a less then optimal setup isn’t going to break my heart with this car. I’m building an LS powered fox that will be more track focused then street and show
