Question GT 40 heads

Quick question on the GT40 heads. How can you tell the difference between them and stock mustang 87-93 heads? We run a spec series and have heard through the vine several of our competitors are using GT40s. Is there something besides the angle of the plugs that give it away?

Re: GT 40 heads

Gt40 or Gt40 P's as in latter models.
The sprint had gt40 iron heads..
The earlier heads had e7 written all over them..

Don't be afraid to try something new. Remember, amateurs built the Ark...Professionals built the Titanic!
