Just Got my 360 Fired for the First time only to find coolant leaking externally near front outer headbolt area appears to be a hairline crack just above headbolt ! Torqued em down in steps and in sequence guess that wasnt good enough ! is it common for these heads ? They where magnafluxed but I think the machine shop missed it I Suspect the Crack opens up only when Heads are Torqued Down Got a Ton of Money in these heads and Just Disgusted !
