I think everyone uses 734's, do a search for Autolite 734 see what you come up with...

I have GT40Ps, and I use Autolite 734s. They're the plug called for with that head. If you're having clearance issues, it's because you don't have the right headers. I have the FRPP headers specifically made for the P heads, and I have no plug issues.

Accel P526s is the part you are looking for. They are about 1/4" shorter I think, but the cheapest I have found them is like $70 for a set of 8.
