Otakubassist Posted August 26, 2007 Share Posted August 26, 2007 Okay, from what ive heard, the H23A1 head dosent breathe all that well. So I was wondering, would a 3 angle valve job and opening up the low end be sufficient, or would a 5 angle be the best bang for your buck? However, it is also a daily driver and needs to pass MD emissions and be reliable. Also, if I got the valve job, what type of cams would you suggest?

..SSR.. Posted August 26, 2007 Share Posted August 26, 2007 5 angle doesn't do jack. All H/F heads flow really well from the factory. Throwing cams in it, you will more than likely fail emissions. Link to comment Share on other sites More sharing options...
