Headers for a 79 big block

[SquareBodyShaun]

Which headers work best for a 454 big block in a 79 GMC Sierra Classic C1500? Was hoping to still use a straight spark plug boot..

Due to the design of the heads, most headers on a big block are going to want 135* boots. Straight boots are close to the primaries and 90* boots tend to put the wires close to the head and can chaff the wires over time.
