GT40p or Gt40 heads with the following;
306 Z-cam Edelbrock RPM with spacer 70mm tb 24Lb inj. Mith Mass Air Mac headers Offroad x Underdrive pullies 255lph Fuel pump
Will these heads work fine on my setup?

I think that since you already have the MAC headers, you should go with the "P" heads to bump up your compression a little. The heads are pretty similar, so whichever are the better deal is what I would go with, especially since your headers will work on either heads.

I could be mistaken but only special model headers work with the gt-40ps. I would double check and make sure that your headers will fit.

And the P heads have a smaller ex. valve- 1.48" The are meant for developing torque in a big vehicle- ie the Explorer.

Would the Edelbrock RPM perform better than GT40 intake or Cobra? What would be the differences?
