Good old carb cleaner will work. You had a leak in the head gasket ? Install a new head gasket and do a compression test and leak down test. Make sure you torque to spec.

Ok thanks and I planned on doin compression and leak test but just spray it? should I hit it with a wire brush or anything? And another question the piston has 67.42 engraved on it is it bored?

Don't use a wire brush, use something plastic so u don't hurt the aluminum. And stock is 66mm so yes it is not stock

I would be advisable the check the head for warpage.

Heads seldom leak unless they have been subjected to overheating or poor tensioning practices.
