Looking For a Head Gasket

I am looking for a head gasket for my 77. The pistons were shot and I found a reasonably priced 3.750 overbore kit so that is what is going in it now. My problem is the head gasket in my set is not right. I remember reading somewhere that if the cylinder hole in the gasket is not the right size, there is a chance of the sleeve breaking and a note came with the kit which says "use a gasket with a 4-4.25" hole." The gasket I have has a 3.75" hole so that won't work. I have looked EVERYWHERE for a gasket and the closest I have got is Denny's Carb Shop which has a whole gasket set for a 770 with a 3.750 overbore for about $360.
Here are some part numbers I know that won't work

160930A/1M181C = Oliver
1919 = Clevite
S186500J = Reliance (this is what I have)

Thanks in advance for any help you guys can offer.
 
I actually got the sleeve and piston kit from a guy on here who had them on his shelf for the last 15 years. As for the gasket, Korves and Maibach do not have it listed online. I might give them both a call and see what I can find out.
