402 big port headers finally found and installed
Found and installed a set of the sbf big port exhaust headers on my 427 sb ford racing stroker. After removing side pipes, the drivers side swaps out from underneath through the void where the header to side pipe flange is, the passenger side through the top.
Another point is that in order to allow spark plug service the inner bolt hole must be used above the plug in order to get a socket over the plug.
No noticeable power difference at pedestrian rpms, but the exhaust note seems cleaner and less puffy(?)...
Also to make new headers that have been coated fit, run a 13/16 drill through the holes to be used in order to clear holes.
