Nice numbers indeed!

Looks like the bowl work, additional compression and split duration cam pay off very nicely.

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.

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+.

How many times are you going to repost this? Did you redyno after fixing the valve float?

2001 Pewter WS6,
Yes this is what valve float looks like on paper. A vacuum guage will start to flutter once valve float/bounce sets in.

Those are some pretty stout #'s.. I just broke a valve spring, bent a valve, and broke a valve guide. I am trying to decide whether to fix what I have or upgrade.. It would be nice if a sponsor would hook a brotha up. I emailed and called a few, but they act like it is the weekend or something..

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.
