OK...most likely a real stupid question...but here we
go.....My 401 
  is in the shop being
bored,balanced...etc. I have INDY SR heads, and 
  an
Edelbrock RPM air-gap intake. They mocked it all up
today to check 
  pushrod length,intake fit...etc.GOT
really WEIRD...the intake gaskets line 
  up just fine on
the heads..BUT are  off on the intake 
  manifold,the
manifolds ports are offset. He says the intake would
have 
  to be welded and machined to line up correctly
with the gasket ports!! My 
  friend who is doing the
machine work says that they run into alot of 
  Edelbrock
port to gasket opening  mis-matching?? NO 
  quality
control????WORST DEAL.........the end rails are 5/8"
off?? There 
  is a 5/8" gap at the point where the
intake end seals are to be????? WTF?? 
  I know the INDY
heads are somewhere around .500 taller than  
  stock
heads...BUT how can the intake surface fit/line up
correctly BUT 
  the ends be that far out of whack??????
Am i missing something here..or is 
  the manifold a
piece of @#*&(^%$#$^&  ?? I have to drive one 
  hour
tomorrow afternoon to the shop to look at this
mess(Thursday). ANY 
  helpful info greatly appreciated.
Please email me or call my cell and leave 
  a message....309-338-3210.Thankyou,Joe
 
Joe,you may have been better off going with the matching Indy intake.
