Default Help with Holley Base gasket choice

I have a Holley 950cfm,4150 carb with a Dominator base on it with 1 5/8 inch throttle bores,the carb is 7 years old and I cannot match a base gasket to this carb,They don,t make it anymore,I can modify a square bore gasket.My question is can I use a thin open gasket between the carb and a 4 hole spacer ?

Sorry I don,t have any Pics of the Carb,I was as baffled as you.I pulled it off a year ago and had it rebuilt,A Holley 4150 complete rebuild kit was used and worked fine.I went to install it with a square bore base gasket the bolt pattern did,nt match up.I determined it was a Dominator bolt pattern,I called the company that built the carb 7 years ago.Bigs Performance Products.Bigs told me the the base was a Dominator base and the gasket was no longer availible. the only thing I can do is match a Square Bore Gasket and modify the bolt holes.My question was will a thin open gasket work with a 4 hole spacer?

Just get a 4 hole gasket and slot the holes. You could also replace the baseplate, BLP has baseplates with a dual pattern 4150/4500 or a straight 4150.
