Not sure why you're being so secretive about the flow #s, etc. It's not like you're class racing and most of the "tricks" that fulco has are going to be the same or similar to any engine builder worth his salt.. As I'm sure a lot of you know, Mid-lift #s are where the power is made (it's where your valve spends the majority of it's time, i.e. it crosses .200-.500 twice vs. peak lift once.) Scot if I were you I would've gone with a different head, those performers have a tiny runner volume and only flow to 230 out of the box, so 30cfm albeit nice is still anemic for your combo. Now I know you'll make up for it with the turbo, but I would've started with a better base head with the combo you're going with (just my .02). Hell, you could've bought my two canfields for the $500 I sold them for, replaced the cracked one for 1k (with all of the work I had done to them) and had a 215cc runner with awsome mid lift #s peaking at 321 @ .700. Of course my last set of TFS-R heads made these look anemic...

Either way, good luck with it..
