best source for carb base gaskets? square and spread bore

sireland67 said
I buy racer pit packs from summit.
Got tired of the local parts store charging $2 bucks each for them.

A while back I went into Oh ' Really's and they had no idea what I wanted, "a square bore Holley pattern 4bbl gasket." "What does that fit?"

"Well for one thing it fits those fancy new Holley carbs you have hanging over there on the display!!"
