I jusat swapped on my ported heads.It's almost a done deal that water is going to get in there.I ran a quart of engine flush (with the old oil and filter),drained the pan,letting everything drip out thoroughly,then added the Syntec and new filter.All good to go.Plus,the engine flush will help get rid of any built up that may be in the engine that you don't know about.Good luck.
