Final Question of the day. Webber 45s Gaskets

[Captain Manly]

Ok, strange question I know but I am not a master engine mechanic.

 

Got my carbs rebuilt and planning to install them, I have 2 sets of gaskets to attach them to the intakes, one set is a typical paper thin and one set are 1/4" thick.  Is there a preference; am I suppose to use the thicker ones for improved air flow (still have enough room for the  brake boost)? 

 

I know SQOTD, but its Monday and not enough coffee.

 

Thanks!!

The 1/4" is a phenolic spacer.  I suggesting using both if there is room, although I can't give  a technical reason why.  I know that sometimes it's necessary to make the linkage work.  My setup has them.

You should use the thick phenolic spacer, because, well, its phenolic.  I think it helps prevents heat transfer from the head to the carb.  And you will need a thin paper gasket on both sides of the thick one.  They can be made from gasket material gotten from your local parts store.
