it will for sure. Since you port heads, a little info on valve angles. No back cut on either intake or exhaust. I was told a back cut brought up the flow up to . 100, but a net loss occurred in the midrange. So i was told don't let anyone change that.





I went to a two day theory only class on head porting years ago and Darren Morgan recommended putting a 30 degree back cut on everything and his reasoning was it will never hurt and usually help. Like I said that was years ago so that thinking may have changed. He has some really good videos on YouTube that I have shared and guys really enjoy them. I have never watched them because by now I know how I want to go about it and after 100’s of flow tests Im kinda set in my ways. I prefer to do it at least on the intake valves. The 30-45 minutes that he spent on the exhaust side was worth the 600.00 plus the 300.00 I spent to take my son.
