Hello and thanks for taking time to read this. I'm in the middle of putting a 455 in a 1969 Cutlass, I had selected Hedman headers because of the spherical fitting and had called Hedman to assure fitment in the car which I was given. Now with the motor in the car, I'm finding that the headers they suggested have multiple clearance issues, at the very least I will be boiling oil in the filter, and burning up the starter on the other side. What headers that are good quality have been used that don't cause all these clearance issues??

Thank you!

Dave

 

Dick Miller has the best headers out there, old Kooks design.
However you will probably still need a mini starter and they will be close to the oil filter.
