Just make sure to put some RTV around the water ports and you'll be fine. And don't over tighten and resist the urge to go more than 144 inch lbs of torque. I re-torqued mine after 6 months because the bolts "just seemed loose". I learned my lesson after changing the oil a few times and replacing the gaskets...144 in lbs is enough. I'm sure that would go for any intake on the Magnum heads.
