77 400 Pontiac Grand Prix Headers
Hello All,
Can anyone give me some information on what Make/Model headers work best for my 400. Cylinder heads are D port Aluminum 72cc heads. Appreciate any advice. Thanks, Gregg |

Did you ever solve this?
I have currently stock log type manifolds but driver side studs are in bad condition and im not sure if RARE / Ram air manifolds fit the GP because of the frame brace diagonal is already really bitch to avoid while trying fabricate downpipe for the current log... |

We put ceramic coated Ram air manifolds on it they worked great.
The head pipes hang a little lower than he would like but they haven't hit the ground as of yet. |

If I remember correctly we just left the lower braces off.
And modified the trans cross over so the pipes would go straight back |
