i have a gs-r with a gs-r head thats port and polished, shaved 30thou, and a 3 angle valve job, aem cam gears, and itr cams, .. i have a opportunity to get a almost brand new charger with headers and intake already for a great price.. i was wondering could i use this charger with this head being shaved 30 thou? or is my compression to high? any experts out there can help me out?

 

bad idea. Been there, tried to stop that from detonating, didn't work. Don't do it
