I will say this one more time. ALL Aluminum engines should use studs, not bolts. I have asked ARP to do a kit for Northstars. No reply yet. Keep radiator clean, which inclueds backwash of the fins. warm the monkey up before driving..Aluminum is a fussy metal, but has the ability to move heat so well that (local) hot spots can get in a bind. This means heads and combustion chambers.
love the Northstar
