A Work Log – The Death and Rebirth of the K20

Head lift at 19-20psi and pushing coolant… that’s how. Had to tear the top end down and torque those head studs down like a boss to keep the head planted. Turns out ARP stud specs aren’t sufficient when you’re pushing 700hp.  

Time to mix up the boost control… 4 port MAC solenoid and 3psi/5psi WG springs.
