Engine painting

This engine's been completely degreased - I'm concerned about remnants of the old paint but ain't sure best way to strip - I'll be removing the intake, exhaust mans, valve covers, maybe oil pan but it ain't leaking now so.......... anyway, any tips ? Good quality paint ? Best exhaust manifold paint (can't do the ceramic $$) ? And does is the pint of POR15 paint really enough for the complete engine ? Lotsa questions here but gettin 'er dun this week ........Thanks
