Headers vs. manifolds

Thank you to all who responded!

For Rumblefish360; engine is a ’99 5.2L Magnum. Block is bored over 0.03” with a higher duration cam (duration @ 0.05 216 intake/224 exhaust), hypereutectic pistons, heavier (LS1) valve springs, and double timing chain. Intake is a Edelbrock Performer air-gap (carb TBD). Tranny is an A904 non-lockup unit rebuilt w/Stage 1 shift kit. Rear end is an 8 1/4" unit (final gearing TBD).

Cheers,
