Chevy Small Block Super Comp Block Hugger Headers
Included Items Note: Bolts, Gaskets and Reducers Included
Port Shape: RD
Emissions Compatibility: Not Street Legal Except Pre-1974
Specifications:
Will these headers fit a 1957 Pontiac 347cu motor? Under vehicle fitment it says that they will fit a 1957 GMC PM151 347cu motor and since these are both 347 GMs I thought that they might work but I was wondering if someone could shed some light.
