Very little if any gains going from l86 intake manifold to lt1. Would be cool if someone did some testing on the l86 intake to see if it actually makes more power than the lt1 intake. I mean they had a lot more clearance to work with when designing the l86 variant.

Our shop truck 2017 L86 Denali gained 26whp 13wtq by going to an LT1 intake manifold and another 23whp and 10wtq going from LT1 to MSD Atomic. Safe to say an L86 truck will gain 49whp 23wtq going straight to the MSD. Final numbers on our Denali were 471/468 FBO+MSD+E85.
