Trick Flow warrants their products to be free from defects in material and workmanship for a period of 90 days from the date of purchase. Assembled high performance street cylinder heads have a 1-year warranty against defects in materials and workmanship.
The upper is identical between the 2 intakes. The difference is the lower due to deck height. You can bolt the 302 upper to a 351 lower just fine.

The Trick Flow R intake will typically make more power than a GT40 on a 351w. The GT40 intake is certainly a good intake, and makes good torque, but the runners are a bit long to maximize upper RPM power.
