Exhaust Manifolds - HO Pontiac \"Round Port\"
Reviews

These are the replicas for Pontiac V8 powered 60's & 70s vehicles with specific "Round Port"  heads.. being an "O" type port opening.

Most were "D"port.. so unless you have say Edelbrock Heads or actual Pontiac Round Port heads these are no good to you..

They are specifically found on 69-74 era Firebird & GTO usually fitted only with performance 400 & 455 motors.

These will fit up to the LH Drive.. 70-81 Firebird that has ROUND port heads.. not the normal D port head.. but ROUND port..

We include the correct manifold pipe flanges in with this deal.

  • The manifolds include two steel flange stud sets and bolts.
  • Due to weight these freight additional from $33 pr, billed later.
  • Please order ahead of time requirement.
