Re: Repost: 439rwhp untuned When I pulled the valves out to install new ones the port work was absolutely incredible. Words can't detail the fine points of these cylinder heads.

Re: Repost: 439rwhp untuned Vince,
I can tell you how to get a set exactly like mine.
When they did the bowls, a couple of ports gained 30cfm while some gained 3-5, end result was they all were flowing the same 310+ & 220+.

Yes this is what valve float looks like on paper. A vacuum guage will start to flutter once valve float/bounce sets in.

Re: Repost: 439rwhp untuned Amazing how the power just off. I have a 236/240 XE-R cam and the top end felt completely flat. The car would not pull. That was with the 987 springs. I now have 977's and Comp-R lifters. I am waiting for my YT rockers to get here. I am anxious to see and feel the difference.
