I was wondering is there any difference good or bad in the gt-40 and the gt-40p heads. I found a set of the gt-40p . The sticky on gt40s did not talk much about gt-40p heads. Thanks
the gt 40 ps have a different spark plug angle, i believe that is the only diff and i hear you can get regular mac headers to fit with a little persuasion.
Yea the headers have to specifically for p heads I got mine fron Mac. The only problem with the p heads are that you need 90 degree boots for the plug wires. The headers are angled close to the plugs.
