i put a 273 kit in my 91 250x now i have to tear it down and i need a new head gasket that is 78mm. does anyone know a website where i can order it, ive been looking everywhere. thanks!

 

where did you get your 273 kit from?

 

je piston from powroll

 

Powroll would have a gasket if you need it. We have a 305 kit in the 300 and I am sure that is the same bore,78mm. We run a stock honda head gasket and have not had a problem at all. I took one head off to put on a big valve head and was surprised to see a stock gasket but put one back in.
