5 of 5 Performance world heads July 5, 2026
Reviewer: Shayne Gervais from Winnipeg, MB Canada  
My machinist said that these were the best set of heads he’s ever seen straight out of the box. I bought mine before they raised their prices. However, his response was “they probably raised their price because they realized that they were offering a great head below their value compered to others.” I’m planning on building another engine for my other project car, I’ll be ordering a large bore Windsor block from PW after seeing how great of a product they sell, along with another set of these heads.
