I think you will find them with and without gaskets. I put one on mine, but had to cut holes to open some of the ports. Seems to work ok. Haven't had it on the road yet.
Question for Hotrod Dad About New 2 BBLs.
Will they bolt right in without any modifications to either the manifold or the linkage. I would like to have one, but I've been working on this thing for over one year, and right now I would just like to get it finished and on the road. I don't need any more aggravation right now. Thanks Allen
