Default Do I need to get my pistons notched with X cam?

Im putting a x cam in my car with portedDO0E 351 heads with heavy valve springs and 1.6 roller rockers. Does anyone know if I will have to notch the pistons for this cam? Also I wanted to a run thin head gasket to boost up the compression a bit do you think this will cause any clearence issues? btw its a stock 89 Shortblock.
