I bought a set of the Summit ram horns for my '70 Blazer that I removed headers from.
They fit well and have a 2½" opening for the exhaust pipe. Plenty of room for the plug wires.
Ironically I have the same SP350/357 crate engine that I'm going to put in that Blazer.
I plan on using the Summit manifolds. You can get them plain, black or shiny.

I got a pair for my 72 and fit well.
The shinny ones
