They were just alloy versions of the gt40. Same tiny port size. If anything the gt40p’s were probably better due to the chamber upgrades over the old gt40’s. Looking back at my Ford Motorsport catalogue from 98 they were the only heads they offered back then. The better, bigger port X heads must not have come along till later. I can find reference to them as far back as 2004 but i don’t know what year they were introduced. So they might not have even been available to tickford at the time of production.
