Head Gasket Job Question

[mikedalcollo]

I'm in the middle of changing my head gasket (at the point of putting it all back together)....when i scraped the block to get all the old gasket off, it got into the the oil and coolant galleries....not to worried about coolant (can rinse easily with water), but the oil....should i be worried about that or will the filter take care of it? I was defiantly going to drain the oil and change that before first start.
Thanks for any advice
