I finally got the exhaust side of my heads done. Although I'am not sure I have this right, so I have questions. On my BBC builds with conventional camshafts I've always wanted lazy low lift flow then have it come on after .300 lift and take off, this has always worked well for me. On my Buick I gained around 12 CFM @ .200 and 12 CFM @ .300 and about 10 CFM @ .400 and finally 9 CFM @ .466 peak lift, will this help me or hurt me?
