400 with TF 240 heads - valley plate options?

Well, thanks for all the info.......and boosting my self image. : / I guess what was throwing me off was the fact that there was a "gap" that needed to be sealed/covered. I figured if Trick Flow was going to make one, then there shouldn't be a gap? Also, the "batwing" set up for AR's plate - with that lip on the bottom? Gave me the impression the lip was helping cover a "gap"? I think Kimmer posted using a 1/4" piece of aluminum. If you make it, I figured a thin skim of rtv and you're good - use some material gaskets on the heads (matched to the ports) and done? Anyway, thank you all for the info. I think I got it now. I'm getting a little older and try to stay current on all the tips, tricks, advances....but I can't keep up. Spending most of my time saving up for and learning about the stuff that was "the best" five years ago....kinda like my "journey"....I can't walk on water but when JESUS calls me, I'm getting out of the boat!
