dpuma8 Posted July 11, 2012 Share Posted July 11, 2012 I bought a P90 head and I noticed that there were some shiny scuff or scrape marks on it. Is this anything to worry about? Does it change anything for me when I put it on the car? They are on multiple areas. Quote Link to comment Share on other sites More sharing options...

letitsnow Posted July 11, 2012 Share Posted July 11, 2012 If you're talking about right next to the valves in the chamber, it looks like machining marks to me. Quote Link to comment Share on other sites More sharing options...
