Bob_H Posted February 11, 2002 Share Posted February 11, 2002 Check out The Datsun Garage and his head pages. Look at the P-79 and P-90 pages. He takes the P-79 and P-90 and tells you what you need to do to get near 10:1 compression. -Bob Quote Link to comment Share on other sites More sharing options...
