    NO GUTS .....NO GLORY !

    Hey I'm installing an aftermarket ROGO HEAD on 580...what spark plugs are recommended for this set up ?

    ...it's a recreational head, so it compression shouldn't be over 175... i wasn't sure if the stock plugs (BR7ES) were up to the task of firing on hire compression,,,second opinions count here!
