I have 9" prop clearance ( I though I was only going to have 7" the min that Van recommends). 
 
Don't tell Van I only have 3" in level attitude :-)  
 
When I went to adjust the gasket prior to putting on the ver 2 lower manifold, I found the gasket on backwards!  I was shocked because that orientation covered approx. 1/2 of the primary and secondary intakes!!  You don't think I flew with it that way while testing my variable length manifold do you - Naaaa!  
 
LOL!  This sounds exactly like something that would happen to me, and it would drive me NUTS wondering if I had flown it that way.  Don't let it bother you though :-)   
 
In any case, I should be ready to fire it up by Monday and do some ground tests and hopefully get airborne during the later part of the week. 
 
Repeat after me- static rpm and MAP :-) 
 
By the way, I don't recall hearing any comments from you about any increase in acceleration on take-off.  Was there any?  I know you indicated the P effect increase was quite noticeable - but how about acceleration?
 
 Oh yeah, plenty of acceleration, but I don't think I ever tried full throttle again after that first takeoff.  When flying level at lower power settings, the acceleration is quite noticeable compared to what it used to be.  I've been pretty severely limited by my restrictive intake, so it will only get better.  
 
BTW, I finished the installation of the new oil cooler, and TB inlets.  I only managed a brief run to make sure nothing was leaking, but it seemed like the mixture was way lean.  Surely it didn't make that much difference.  Tomorrow, I'll tie it down, and check the tune, and static rpm.  I'm really happy with the way the inlets came out, and I'll be even happier if they actually work.
