IMO, if I were building an engine, I'd use the Twisted Wedge heads or the latest design from Ford guru Jon Kaase...... The Edelbrock Performers wouldn't be bad IF you already had a set of "pedestal" type aluminum roller rockers.......

The Trick Flow aftermarket heads are way better then the GT40's, but between the Trick Flow & the Edlebrock, it's close. I prefer the Trick Flow, & have them on my '89 hatch, but that's me.
