Do the GT40P's have that big bump in the exhaust port like the standard GT40's do? I thought a saw a post where a guy said he ground out the big bump in the exhaust port of his GT40P's when I thought the "P's got rid of that becaust they had no EGR passages and that is why the exhaust port flowed so much better than the regular GT40's. Tell me what is right. Thanks

They do still have the bump but it is not as large as other factory ford heads and is easy to remove.

There is a small "potrusion" in the top of the ports but it is nowhere near as pronounced as with other heads. I have seen flow data where it was removed and no gain was made, so it must not be much of an obstruction to flow. I didnt even bother to grind mine out when I put my P's on.
