i am about to fit gt40p heads on my old girl and some goose told me they wont fit my factory headers because of the different spark plug angle.is this true because i thought these were the heads fitted to eb gt
GT40 heads were on the EBGT, GT40P heads were on the AU's.
The P heads had the different spark plug angle so your factory headders will not fit.
Good excuse to upgrade your factory headders with some decent extractors as the factory headders should be the first thing to go.
And yes do a search, as these forums have an extensive archive of information waiting to be tapped...
