302 mustang heads in Tritan V8

....what he said.

Tell your friend he's going to want to look into a set of '99-up PI Windsor heads for his Truck. Assuming his engine hasn't got them already, the PI castings will bolt on just like his previous ones, but will give him a significant power jump.

What per say is wrong with his current heads? The modular aluminum heads are known for stripping the spark plug threads on occasion, but this can be repaired with a little JB weld and a Helicoil insert along with the use of AGSF plugs in place of the old AWSF ones?
