<VV> 1960 to 1961 Cylinder Head differences

[Rt66Vairs at aol.com]

I already have bakelite spacers on the Lakewood now and the carbs were  
rebuilt just a few hundred miles ago so I plan to go with them. Also have a box 
 full of carb carcasses along with several bakelite spacers.
 
Wouldn't use any other kind.

This isn't just a  suggestion... ;)   It's damned near mandatory.   Do  
NOT use that aluminum spacer.  There's a good reason GM dropped it  
quickly... and with today's somewhat volatile gasoline it's even 
worse  for carb boil-overs.  Use the black carb spacer.   with two  
gaskets, not bare, one on each side of the spacer.

The gaskets help  insulate the carb more than they actually help seal 
vacuum  leaks.   The carb flange and a fresh decent carb base are both  
machined close enough that you'd likely get away with not using any  
base gaskets at all and not have a noticeable gasket leak.    I've 
seen lots of 'Vairs with just the bakelite spacer and no gaskets,  
running just fine.

Still, anything to help prevent carb  overheating/heatsoak and the 
accompanying boil-over will help make it  restart easier in warm 
weather after it sits for a few minutes.   ...not to mention the 
wasted fuel that drools down the carb throat as it  percolates in the 
hot carb bowl.
