Magnum Adventure

Head cracking issues abound from every auto manufacturer there is at any given time on a y engine. Many peoe here love to trash the Magnim head as prone to cracking and offer nothing but repeated statements of the issue.

I have had J heads crack, '68 Ford 302 heads crack. Cooling the engine is what needs to be done effectively in order to avoid any head cracking issues.
Whe some heads are more prone to cracking, the crack can be of little issue or a catastrophe.
