One owner found there was no off-the-shelf 4bbl intake for C-3 heads after 
he'd bought them, and wound up buying Quella's EFI system as a 'best 
alternative' for $4600 extra... on top of a $1000 Jesel rocker system. Both needed 
some rework to actually make the Cleveland run. The intake alternative was a 
'blank' intake that needed substantial machining everywhere to fit. This 
was a few years ago, so maybe the supply has changed, but I'd check real 
closely before buying brand new C or D- SVO heads. Real-racing parts are uncommon 
and expensive but sometimes you can get used package deals that includes 
some of the hi-buck stuff. As Julian said, the problem with racing heads & 
intakes, you don't know if that motor was ported for Martinsville where the 
cars run 9600 rpms all race, or Talledega where they turn a max of 6500. FWIW-
