Both the 260hp and 280hp motor used the same head. 1.92/1.66 valves and 68cc.

Hey Jay, While you are on the topic of this engine. Do you know if these two engines used the same camshaft also? Thanks, Rick

Thanks for the reply, that'a what I thought but I wasn't sure

Poncho_Villa, I believe they used the same cam.

Thanks John, I was just a bit curious as to the difference between a 326 HO and a 326 with a 2 barrel carb. Obviously the induction, but thought maybe the HO would breath better with more lobe lift and duration from a factory cam. Do you know if the HO came with duel exhaust? Rick.

Hmmm, I though the HO engine used a little more camshaft too. At least mine will when it goes back together!!!
