'79 exhaust manifolds

[Bob_K]

Are the L-48 and L-82 exhaust manifolds the same for a '79, or do the L-82's have larger inlets/outlets?

I am fairly certain the l48 are 2 " and the L82 are 2.5 thats the way it is for my 75

All Corvette small-block exhaust manifolds from 1966-on have 2" outlets; last usage of 2-1/2" outlet manifolds was in 1965.
