cool! Thanks man. I found that even in PE mode, the pcm was ADDING desired a/f ratio less than 50% throttle. Adding back 2-POINTS from my target 11.7 whic is 13.7!!!! At 16psi boost even at 35-40% throttle (medium load) 13.7 is WAYYY to lean. I had fixed this last summer when I started tuning with HP tuners. My transmission is stand-alone now, Full manual shift automatic. www.e-transcontrol.com

Well, I finally got around to putting this thing back together. I splurged for a set of ss oversize valves. I had them installed and the heads cleaned-up. Here'* what I am putting back on the engine. I am using Cometic gaskets prepped as per ZZP recommendations. The valve installed height came in about .025" shorter than stock... I am hoping the lifters have enough pre-load to take up the slack. If not, I will need new, longer pushrods.

Now that looks sexy, I like a lot. You pushed those valves right to the limit. Should give you a ton of flow.
